Trusted teacher: Thermal changes accompanying physical and chemical changes Thermal changes accompanying physical changes - melting temperature It is the temperature change when one mole of solute is dissolved in a given amount of solvent (The amount of heat energy absorbed or released when one mole of solute is dissolved in a given amount of solvent). During the dissolution process: two processes occur: A- Dissociation: the breaking of bonds (endothermic reaction) Sodium and chloride ions dissociate from the crystal lattice as a result of the ionic bond breaking. The energy absorbed to break the bond is called the heat of the crystal lattice (bond energy). - Crystal lattice temperature: It is the energy needed to break the bond between ions in the crystal lattice. B- Hydration: The dissociated ions bind with water molecules to form hydration ions (exothermic process). Rehydration temperature: It is the amount of heat released when hydrating ions bind to water molecules. If the crystal lattice temperature > heat of hydration Dilution temperature: It is the heat change per mole of solute when diluted from a concentrated solution to a dilute solution. (It is the heat change of one mole of solute when diluted in a large amount of water (about 1000 moles of solvent)). Sedimentation temperature: The amount of heat released when one mole of an insoluble substance is completely precipitated. - heat of combustion It is the amount of heat released when one mole of a substance is completely burned in an abundance of oxygen. (The reaction is always exothermic). Formation temperature: It is the amount of heat released or absorbed when one mole of a compound is formed from its elemental elements so that the elements are in their standard state. (at 25 °C, a pressure of 76 x g). Note: Heat of formation of the elements = zero

Benoit - Limoges, FranceRecently active40€
40€Private online mathematics lessons - Qualified and experienced teacher
Trusted teacher: I am a qualified and experienced mathematics tutor. Graduated from the Free University of Brussels in 2011, I started my career by teaching remedial courses in different schools in Brussels. I then specialized in individual academic support by following educational training at the Harvard Graduate School of Education. I have been giving private mathematics lessons daily for over ten years. The students who follow my private lessons benefit from personalized support. The first session is devoted to an in-depth assessment of the student's mathematical knowledge. The objective is to detect its weak points and understand their origin in order to adapt my courses to its needs. I develop a tailor-made remediation program for each of my students aimed at filling each of their gaps. Over the course of the sessions, the student builds a solid foundation for learning and regains self-confidence. At the same time, I help him acquire a work methodology that allows him to gradually become autonomous in his studies. I have a perfect knowledge of the mathematics program of the College and the High School (from the Sixth to the Terminale). During my formative years, I studied and developed many techniques that make it easier to learn math. The strength of my pedagogical approach lies in my ability to explain in a simple way everything that the student finds complicated. I am passionate about this job because it gives me the opportunity to guide dropout students on the path to success. It is a real pleasure to see them evolve and come to terms with the fantastic world of mathematics. I provide my private lessons in Limoges (at the student's home) or remotely (online via the internet). My distance learning courses take place on an interactive online whiteboard. This board is specially designed to promote student/teacher interaction on the internet. Thanks to this educational tool, my online courses are as effective as home courses. The student only needs an internet connection and a computer, tablet, or smartphone to take advantage of it.

Private online mathematics lessons - Qualified and experienced teacher (Limoges)
Benoit
Benoit is friendly and patient and has a good sense of when to challenge and when to take a step back. My son, who is 8, really likes his lessons very much. He loves math, especially working with big numbers, and at school it isn't always possible to work on calculations as he would like. After few lessons he already learned new techniques for calculations he likes to experiment with and Benoit also managed to challenge him to try some new and more advanced things. I think this type of lessons is more tricky to prepare, at least until the teacher gets to know well the capacities and character of the child, as there are not based on the child's curriculum or homework to be done. Benoit is always open to discussion and if my son finds something too challenging, they take a step back and try another way or just agree to try another time when my son feels ready for it.

Private French lessons for adults and teenagers with native French speaker in Co. Mayo (Newport)
Phillip
It is always a pleasure to meet Phil for our weekly online French classes. He is a patient and kind teacher and always full of energy for our class. Phil is interested in a wide range of topics, so we always have something to talk about based on an article he selected as 'homework'. What I really appreciate about his way of teaching is that he corrects me during our conversation without breaking the flow of our talk, so I can really feel my confidence in speaking French increasing each class. I woulf highly recommend Phil if you are looking for a French tutor :)

Private coding / programming lessons with python (Paris)
Matías
Highly recommended teacher!!! Matias teaching methods are great. Very clear and concise. Doesn’t waste your time explaining meaningless background information and always lectures with the intent to help you understand the material. He’s helped me understand content for my master course on Python and is one of the best lecturers that I’ve had. Your passion and dedication is beyond words! Thank you for getting me through this hard quick semester, I honestly would have never passed if it was not for your help! Thank you so much once again!
