How is firing photons at the surface of a metal analogous to rolling different types of balls (ping pong, tennis, soccer, etc.) at a set of bowling pins?

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Why is nh3 classified as a polar molecule

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
