Laboratory Manual. Montana State University-Billings. Lab # 1 Specific Heat and Calorimetry. Theory: The specific heat (c) of an object is defined by the equation that relates the heat energy (Q) absorbed by an object of mass m to its corresponding increase in temperature (∆T): Q = mc∆T.
The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.

The source of solar power is energy carried by the electromagnetic waves radiated by the Sun. Most of this energy is carried by visible light and infrared (heat) radiation.
Textbook Solutions. CBSE Notes. What is Energy? Energy is one of the most important entities in our universe. We perform many day to day activities. Think, what causes humans to do all the daily activities? This capacity or ability of a body or system to do work is referred to as energy.
SOURCES AND EFFECTS OF HEAT ENERGY STUDENTS’ LEARNING OUTCOMES After studying this chapter, students will be able to: þ Describe the sources and effects of heat. þ Explain thermal expansion of solids, liquids and gases. þ Explore the effects and applications of expansion and contraction of solids.
The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, (14.2) where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.
