A hot just-minted gold coin is places 210 g of water to cool. The water initial temperature is 25° C. After a couple minutes the system water-coin reach a temperature of 33° C. What is the mass of the coin? The specific heat capacity of the Gold is 129 J/kg•°C, show your procedure.​

b would be the answer

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
