The change in internal energy of the system is 1644 Joules.
<u>Given the following data:</u>
To find the change in internal energy of the system, we would apply the First Law of Thermodynamics.
Mathematically, the First Law of Thermodynamics is given by the formula:
Substituting the values, we have:
<em>Change in internal energy, </em><em> = </em><em>1644 Joules.</em>
Therefore, the change in internal energy of the system is 1644 Joules.

Hello!
The number of 20-g ice cubes required to absorb 47 kJ from a glass of water upon melting is 7 icecubes
Why?
We are going to clear from the equation of the released heat, the mass of ice (m). The specific latent heat of fusion of ice is 336 kJ/kg:
So, 7 ice cubes are required to absorb that amount of heat from the glass of water.
Have a nice day!
Answer:
about the same
Explanation:
Thermal energy is constant at a certain temperature in general. The energy is denoted by
Where,
is the Boltzmann constant
T is the absolute temperature
Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.
Thus,
The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.
