Identify when an object has a kinetic energy of zero joules. Question 2 options:

A. as a pendulum swings downward.

B. when the energy has been destroyed.

C. just after a ball it leaves your hand pitching a ball.

D. when an object is no longer in motion.

Amixture that has two or more substances that are spread out evenly is called a. compound b. heterogeneous c. substance d. homogeneous

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.

Calculate the temperature rise when 0.2g of propane is used to heat 400cm cubed of water.
