10. Which of the following is accurate when discussing specific heat? O A Soeric heat values for liquids will never vary for different ranges of temperature,
B. Specfic heat values for solids will never vary for different ranges of temperature.
C. The spect chest of a gas can be measured at constant pressure.
D. The specific heat of a gas can be measured at constant volume only

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.

Which model displays the change in a gas when the temperature of the gaseous system decreases?
