Aglass flask whose volume is 1000 cm3 at a temperature of 0.200 ∘c is completely filled with mercury at the same temperature. when the flask and mercury are warmed together to a temperature of 52.0 ∘c , a volume of 8.50 cm3 of mercury overflows the flask.
if the coefficient of volume expansion of mercury is βhg = 1.80×10−4 /k , compute βglass, the coefficient of volume expansion of the glass.
express your answer in inverse kelvins.

pretty sure it's false

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.
