Question 6 (1 point) As liquid water freezes, what happens to its thermal energy?

Thermal energy decreases because potential energy is decreasing.

Thermal energy remains constant and kinetic energy decreases.

Thermal energy decreases because kinetic energy is decreasing.

Thermal energy remains constant, and potential energy decreases.

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

The ability to make things happen is also called a. heat b. force c. matter d. energy
