A sample of a gas is expanded to twice its original volume while its temperature is held constant. Relative to their original average energy, the new average energy of the molecules is

Lesser as it drops based on increase in volume

Explanation:

Kinetic Energy is directly proportional to temperature. so since the temperature is held constant and volume increased, Temperature would drop and kinetic energy would reduce

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,
