    00:05 Internal energy relates to temperature using specific heat capacity
    00:39 Heating a substance increases its internal energy.
    01:13 Internal energy determines temperature
    01:48 Specific heat capacity measures energy needed for temperature change
    02:22 Internal energy equals mass times specific heat capacity times change in temperature
    02:56 Calculating change in temperature using specific heat capacity of water
    03:32 Converting energy units and calculating final temperature change.
    04:04 Energy loss to surroundings affects temperature change
