A certain amount of heat is transferred to2 kg of aluminum, and the same amount of heat is transferred to 1 kg of ice. Referring to Table 16-2, (a) is the increase in temperature of the aluminum greater than, less than, or equal to theincrease in temperature of the ice? (b) Choose the best explanationfrom among the following:I. Twice the specific heat of aluminum is less than the specificheat of ice, and hence the aluminum has the greater temperature change.II. The aluminum has the smaller temperature change since itsmass is less than that of the ice.III. The same heat will cause the same change in temperature

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
