A substance with specific heat 0.2 cal/(g ⋅°C) which is initially at 70 °C comes into contact with the same amount of another specific heat substance 0.5 cal/(g ⋅°C). The final temperature when equilibrium is reached is 46 °C. Calculates the initial temperature of the second substance.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
