D. Sweat evaporating from the skin cools the body because so much heat is removed while it evaporates
Answer:
B. it accounts for all the energy in the good even if some of its largely excreted by th body
Styrofoam is composed of mostly of air, this means that it is a poor conductor. It traps air in small pockets, stopping the flow of hear energy, making Styrofoam an excellent insulator!
Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
