The specific heat capacity of gold at 25°c is 1.290×10-1 j/g/k.
for a 5.25×102 g sample of gold, how much will the temperature increase if 6.908×102 j of energy is put into the system?
(assume that the heat capacity is constant over this temperature range.)

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
