a 250 g block of ice is removed from the refrigerator at -8.0°C. how much thermal energy does the ice absorb as it warms to room temperature (22°C)? (the heat of fusion of water is 334) (specific heat of ice is 2.05 joules/gram) (specific heat of water is 4.184 joules/gram) (besties pls help, this is like my third time posting this and no one answered 3)

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output
