Nuclear energy is produced when scientists force uranium (U) atoms to break apart. With this in mind, examine the list below. If scientists were to break apart each of the items on the list, which items would still be classified in the same way? Which items would be classified differently? Consider the definition for each as you respond.
• atoms
• elements
• compounds
• molecules
• matter

The heat required for the given process is 2659.3 kJ

Explanation:

The processes involved in the given problem are:  

Pressure is taken as constant.

To calculate the amount of heat absorbed at different temperature, we use the equation:

       .......(1)

where,

q = amount of heat absorbed = ?

= specific heat capacity of medium

m = mass of water/ice

= final temperature

= initial temperature

To calculate the amount of heat released at same temperature, we use the equation:

      ......(2)

where,

q = amount of heat absorbed = ?

m = mass of water/ice

= latent heat of fusion or vaporization

Calculating the heat absorbed for each process:

We are given:

Putting values in equation 1, we get:

Converting the latent heat of fusion in J/g, we use the conversion factor:

Molar mass of water = 18 g/mol

1 kJ = 1000 J

So,

We are given:

Putting values in equation 2, we get:

We are given:

Putting values in equation 1, we get:

Converting the latent heat of vaporization in J/g, we use the conversion factor:

Molar mass of water = 18 g/mol

1 kJ = 1000 J

So,

We are given:

Putting values in equation 2, we get:

We are given:

Putting values in equation 1, we get:

Total heat absorbed =

Total heat absorbed =

Hence, the heat required for the given process is 2659.3 kJ
