The temperature of a sample of matter is a
measure of the
(1) average potential energy of the particles of
the sample
(2) average kinetic energy of the particles of the
sample
(3) total nuclear energy of the sample
(4) total thermal energy of the sample

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Imagine one batch of soup (batch “a”) is made with 8.19 g/can of salt, according to the recipe, and a second batch of soup (batch “b”) is made with 8.32 g/can of salt. explain which batch would be more resistant to frost damage if it is shipped a great distance in winter and explain why.
