You also have the option to opt-out of these cookies. A gass temperature is a measure of the average kinetic energy of its particles. True or False, Radiation requires matter to transfer energy. See. (f) The energy of the universe is constant; the entropy of the universe decreases toward a minimum. Higher temperatures can also cause a transition to a different thermodynamic "phase," most likely a liquid phase. Its dimension will change with temperature, say from 0C to 200C; it will remain solid, but will expand with increasing temperature. What's the force of the moon's gravity on the probe? When we supply heat energy to the liquid, the particles of water start vibrating even faster. Why does temperature remain constant during phase changes? What happens to matter when its temperature decreases? As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Due to statistical behavior, the density of the gas tends very quickly to be isotropic within that container. C. velocity of molecules within a body. Edit. Which is correct poinsettia or poinsettia? How does the change in temperature affect matter?
