Document Summary

We attribute the quantity of temperature to the kinetic energy of the particle in a gas. +kb = boltzmann constant 1. 38 times 10 to the negative 23rd power j/k. 1st la(cid:449) is the (cid:862)you (cid:272)a(cid:374) (cid:271)reak e(cid:448)e(cid:374) la(cid:449)(cid:863) 2nd la(cid:449) is the (cid:862)you (cid:272)a(cid:374) (cid:271)reak e(cid:448)e(cid:374), o(cid:374)ly at 0k(cid:863) 3rd la(cid:449) is the (cid:862)you (cid:272)a(cid:374)(cid:374)ot rea(cid:272)h 0k(cid:863) Calorie: amount of heat needed to raise 1 gram of h2o by 1 degree celsius. +or 1 pound of h2o by 1 degree fahrenheit.
