Temperature and Heat and Energy

AI Thread Summary
Heat is defined as the transfer of thermal energy, which is the energy linked to the random motion of atoms and molecules. Temperature is a measure that relates to the average kinetic energy of gas particles, expressed mathematically as 1/2 mv² = CΔT, where C is a proportionality constant. The discussion emphasizes the distinction between kinetic energy and thermal energy, clarifying that while kinetic energy pertains to the motion of individual particles, thermal energy encompasses the collective energy of all particles in a substance. Additionally, it highlights that temperature is not the same as heat; rather, heat is the process of energy transfer due to temperature differences.

Heat is the transfer of thermal energy.

Thermal energy is the energy associated with the random motion of atoms and molecules.

Temperature is related to kinetic energy in the following way:
The average kinetic energy of a gas is directly proportional to the absolute temperature:
1/2 mv2 = C\DeltaT, where C is the proportionality constant.


How is kinetic energy different from thermal energy?

How is temperature different from heat (thermal energy)?

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
