FAQs on Textbook: Heat and Temperature - Technical Science for Grade 10

1. What is the difference between heat and temperature?
Ans. Heat is the energy that is transferred between substances or systems due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance. Heat is measured in joules, whereas temperature is measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).
2. How does heat transfer occur?
Ans. Heat transfer occurs in three main ways: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection involves the movement of fluid (liquid or gas) that carries heat with it. Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.
3. What is thermal equilibrium?
Ans. Thermal equilibrium is the state reached when two objects at different temperatures are in contact, and heat transfer occurs between them until they reach the same temperature. At this point, there is no net heat flow between the objects, and they are said to be in thermal equilibrium.
4. How does specific heat capacity affect temperature change?
Ans. Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Substances with high specific heat capacities require more energy to change their temperature compared to those with low specific heat capacities. This means that materials like water can absorb a lot of heat without experiencing a significant increase in temperature.
5. What are the states of matter and how do they relate to temperature?
Ans. The states of matter include solid, liquid, and gas, and they relate to temperature through the kinetic energy of their particles. In solids, particles are closely packed and vibrate in fixed positions; in liquids, they are close but can flow past each other; in gases, particles are far apart and move freely. As temperature increases, the kinetic energy of the particles increases, leading to phase changes such as melting and boiling.
