Two samples of 2.0 L of water are heated by adding 50.0 J of thermal energy to each. Both samples are at the same pressure, 1 atm. What are the possible initial temperatures of the two samples?

Based on the position vs. time graph which velocity vs. time graph would correspond to the data

Consider the nuclear equation below. 239/94 pu—-> x+ 4/2 he. what is x?

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?
