Energy transfer

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.

She challenges Tamiko to answer this question: If a bimetallic strip is made of steel and brass, which way will the strip bend when it is heated, and why?
"The strip bends toward the steel, because a steel is larger than abrass"
"The strip bends toward the brass, because a steel is larger than abrass"
"The strip bends toward the brass, because abrass is larger than a steel
"The strip bends toward the steel, because abrass is larger than asteel"
41
Tamiko is correct. From AL = aLAT, as the temperature increases, brass will expand more than steel because abrass steel Therefore, the strip bends toward the steel.
