Answer:
A. There is a temperature difference
Explation:
Whenever there is a temperature difference, heat transfer occurs. Heat transfer may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice chest.
Answer: At very low temperatures, gases expand less for a given pressure change than they do at high temperatures.
Explanation:
So, for compound with composition <span>NH3O</span> the correct structure would be <span>H2N−OH</span><span>. The structure of second type is stable for compound </span><span>NOF3</span> and may be observed for amine oxides like (C2H5)3N→O<span> or pyridine-N-oxide.

You can say that if the volume of the gas is halved, the pressure is doubled.
The expression shows that pressure and volume are inversely proportional if temperature and amount of gas is held constant. This means that if volume goes down the pressure needs to go up. That also means that in order to maintain the K value, if pressure is doubled the volume needs to be halved and if the pressure is halved the volume needs to be doubled.
This relationship only works if we assume everything else (Temperature and moles of gas) to be constant.
I would say copper, silver, and tin, since an alloy is a mixture of metals and metalloids.
