A piston is charged with gas and locked into place. The pressure of the gas is initially measured as 815 mmHg at 294K. The piston is then heated to 307K. What is the new pressure of the piston?

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
