If you pour equal amounts of scalding hot water into different metallic cups of equal temperature, which cup will heat up the most? rank the cups from hottest to coldest. rank from warmest to coolest final temperature.

There are no choices given but we can still have an answer for this problem. We can assume that each choice is a cup that is made of different metal. Metals are very good conductor of heat but different metals are better. Thermal conductivity is the information we need to know here. The higher the thermal conductivity the faster the cup will increase it's temperature.
