A 61.35g piece of boiling (100C) metal is placed into a calorimeter which is at room temperature (20.0C) and contains 50g of water. The final temperature is 37C. What metal is it?

D-no effect on the rate

The answer is the third choice

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
