The water molecules in a cup of hot coffee have a higher average kinetic energy than the water molecules in a cup of iced tea, which also means they are moving at a higher velocity.
How much energy does it take to make a cup of tea?
A typical cup holds around 250 ml of water and, given that room temperature is around 21 C, I want to raise it 79 degrees to boiling point. So, the total energy required to heat this cup of tea/coffee is: 4.184 * 250 * 79 = 82,634 joules.
How much money does it cost to make a cup of tea?
