Block A is a 50-g aluminium block origin...

Block A is a 50-g aluminium block originally at `90^@C`. Block B is a 100-g aluminium block originally at `45^@C`. The blocks are placed two separate 1.0 litre containers of water that were originally at `20^@C`. When the systems reach thermal equilibrium, which aluminium block will have the higher final temperature?
