07 (part 1 of 2)
An ideal gas, initially at a volume of 5.33333 L and pressure of 9 kPa, undergoes isothermal expansion until its volume is 6 L and its pressure is 8 kPa. Calculate the work done by the gas during this process. Answer in units of kJ.

008 (part 2 of 2)
Find the heat added to the gas during this process. Answer in units of kJ.

the answer would be c. motion and direction

i hope this : )

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
