B.72.3
C.68.2
D.34.8
Answer:
According to Brittanica, "Internal energy [is] the property or state function that defines the energy of a substance in the absence of effects due to capillarity and external electric, magnetic, and other fields."
Phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This process involves the modification of kinetic energy and intermolecular forces.
The relationship between phase changes and temperature or heat energy is that phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This is based on the theory of kinetic energy and intermolecular forces. For instance, when ice melts to become liquid water (also known as melting), it does it at a specific temperature which is 0 degrees Celsius under 1 atm pressure. During this phase change, the ice absorbs heat energy from the surroundings without changing its temperature.

Answer:
60N
Explanation:
You use the equation F=AM where F=Force A=Acceleration and M=Mass
You multiply the Acceleration (1.5) and the Mass (40) together and that gives you 60N as the force
