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 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
