In an experiment to determine the specific latent heat of fusion of ice using a container with negligible heat capacity, a student obtained the following data:
Initial temperature of water = 30 °C
Final temperature of water + melted ice = 20 °C
Initial mass of water = 100 g
Final mass of water plus melted ice = 110 g
(i)Calculate the heat lost by the water.
ii) Calculate the heat gained by the melted ice.

statement #3 on andre"s list is 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.

it's a b and
