What is the value of x in the measure of the angle?
Andrew [12]
The two angles would be both 41 degrees.
(2x  + 13) = 41 \\ 2x = 41 - 13 \\ 2x = 28 \\ x =  \frac{28}{2} \\ x = 14
x in this case would be 14 degrees.

A system gains 687 kJ of heat, resulting in a change in internal energy of the system equal to 156 kJ. How much work is done?
Maslowich

Answer:

w = -531 kJ

1. Work was done by the system.

Explanation:

Step 1: Given data

  • Heat gained by the system (q): 687 kJ (By convention, when the system absorbs heat, q > 0).
  • Change in the internal energy of the system (ΔU°): 156 kJ

Step 2: Calculate the work done (w)

We will use the following expression.

ΔU° = q + w

w = ΔU° - q

w = 156 kJ - 687 kJ

w = -531 kJ

By convention, when w < 0, work is done by the system on the surroundings.
