Report

A kilogram of aluminum metal and a kilogram of water are each warmed to 75 C and placed in two identical insulated containers. One hour later, the two containers are opened, and the temperature of each substance is measured. The aluminum has cooled to 35 C, while the water has cooled only to 66 C. Explain this difference.

Aluminium cods quicker then waterAluminium hss alover heat capacity.

So this question tells us that we have two identical insulated containers, one with aluminum and one with water, and they're both heated to seventy five degrees Celsius. And then we allow them to sit for one hour. And then after this our aluminum has cooled to thirty five degrees Celsius. But our water has only cooled to sixty six degrees Celsius and asked to explain why there's this difference and the reason is that aluminum cools quicker than water, and so, given this one hour time frame, the aluminum cools much quicker, and so it's at a lower temperature after just one hour. And the reason for this is that aluminum has a lower heat capacity, so he capacity refers to the amount of heat it takes toe warm a substance, but also means that it will lose that heat Justus quickly. And so because aluminum has a lower heat capacity, it doesn't hang on to that heat as much as the water does, resulting in the difference and temperatures
