In this diagram, heat energy is being added over time. The vertical axis shows an increase in temperature, and the horizontal ax
is shows the passage of time. What is happening to the temperature at Point B?
1. The temperature is rising as the molecules break apart from each other.
2. The temperature is not rising because the heat is being used to break the connections between the molecules.
3. The temperature is dropping as the molecules break apart from each other.
4. The temperature is not rising because the molecules are slowing down.

The potential energy of the lemming is 1.53 J
Explanation:
The potential energy (PE) of an object is the energy possessed by the object due to its position in the Earth's gravitational field, and it is given by:
where:
m is the mass of the object
is the acceleration of gravity
h is the height of the object relative to the ground
In this problem:
m = 0.0780 kg is the mass of the lemming
We want to find the potential energy when the height is
h = 2.00 m
Therefore, we find:
