Explanation:
The heat of the water is shared with the ice and there for you drink will get cold but your ice will melt away from the heat going in the ice
I change the coefficient 2 to 2 times 2 that will give me 4 so at this point on each side of the equation I have the same number for each type of atom that means this equation is balanced.
Among the choices, the unit of energy is calories. Answer in 1) is D. In 2) we are given with te mass , heat and temperature change. we just need to get the heat capacity and compare it with the following metals. The calculated heat capacity is 0.46 kJ/kg K. The answer is A. iron. In 3) we can compute the heat absorbed by the formula ΔH=mCpΔT. Cp of water is 4.18 J/g K. Answer of 3) is D. In 4) the formula used in Cp=ΔH/mΔT. Answer in 4) is A. The heat of enthalpy of fusion of ice is 80 cal/g. We convert this to J/g. Answer in 5) is B.334 J/g.
