There are 2 pans of water, one has 10 mL in it and one has 500 mL. You add 3000 joules of energy, which one has the bigger change in temperature?

The change in temperature is bigger for the first pan which contains 10 mL of water.  

Explanation:

in one pan

mass, m = 10 mL = 10 g

in another pan

mass, m' = 500 mL = 500 g

Heat, H = 3000 J

Specific heat of water, c = 4.2 J/gC

Let the change in temperature in first pan is T and in the second pan is T'.

Use the formula of heat

H = m  c T

For the first pan

3000 = 10 x 4.2 x T

T = 71.42 C

For the second pan

3000 = 500 x 4.2 x T'

T' = 1.42 C

So, the change in temperature is bigger for the first pan.

d. learned preferences i believe is your answer

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.
