Calculating the final temperature after heat is added to a block.

A 2 kg block of aluminum is originally at 10 degrees C. If 140 kj of heat is added to the block, what is the final temperature in degrees C?

Calculating how much ice melts after hot water is poured over it.

7 kg of water at 90 degrees C is poured into a very large (much more than 7kg) block of ice which is at 0 degrees C. How much (in kg) ice melts?

Calculating the equilibrium temperature of two substances.

A 10kg aluminum block of (c=920J/KgC) at 75 degrees C is dropped into 100kg of water ( c=4186J/kgC) at 50 degrees C. Assuming the heat only passes between the water and the aluminum (no losses) what will the equilibrium temperature (in degrees C) be?

Calculate the binding energy per nucleus of this boron nucleus

The mass of the boron nucleus is 11.00657 u. The sum of the masses of the 5 protons and 6 neutrons in this nucleus is 11.08837 u. Calculate the binding energy per nucleus of this boron nucleus. (1 u = 931 MeV) Either: A) 0.0180 MeV B) 76.16 MeV C) 11.381 MeV D) 7.616 MeV I need you to explain to me how to set up and solve this problem. Thank You.
