Answer 1

For 47.30 grams of copper to freeze, 9,697 joules of heat are expended.

What is liquid nitrogen's latent heat of vaporization?

The calculated latent heat of LN2 is -5.59 kJmol-1, which is 0.38 kJmol-1 less than the experimental result and 2.38 times the experimental error.

How can you figure out how much heat is in each gram?

The formula: can be utilized to determine energy. Q = mc ∆T. In the equation, Q stands for energy expressed in joules or calories, m for mass expressed in grams, c for specific heat, and T for temperature change, which is the difference between the final temperature and the initial temperature. Water has a specific heat of 1 calorie/gram °C.
