Why does water in a can stay cooler if the can is wrapped up in a wet cloth? Explain.

53,130 J

Explanation:

When a certain substance absorbs heat, the temperature of the substance increases according to the equation:

where

Q is the amount of heat absorbed

m is the mass of the substance

C the specific heat capacity

the change in temperature of the substance

In this problem:

m = 2.3 kg is the mass of copper

is the increase in temperature

is the specific heat of copper

So, the amount of heat absorbed is:

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
