If we increase the temperature of the tank to 85C, what will the new pressure be inside the tank?

The new pressure will increase.

Explanation:

If the temperature in a tank increases, the pressure inside the tank will also increase. This is one of the postulates of the general gas law.

Pressure exerted by a gas is it's force per unit area.

When we reduce the equation of the combined gas law taking the number of moles to be 1, we see that;

  "at constant volume, the pressure of a given mass or mole of gas varies directly with the absolute temperature" .

    The higher the pressure, the higher the temperature will be.

Since the complete parameters are not given, use this expression below:

         

where P and T are pressure and temperature

           1 and 2 represents initial and final states.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
