Answer 2

Answer:

The sol, with explanation:

1. heat                 - c

2. temperature   - d

3. absolute zero  -a

4. latent heat       -b

Explanation:

1. Heat refers to the energy that is transferred between two objects or systems as a result of a temperature difference. Heat always flows from a hotter object to a cooler object, and can be transferred by conduction, convection, or radiation. The amount of heat transferred is determined by the temperature difference, the properties of the materials involved, and the amount of material present.
2. Temperature is a measure of the average kinetic energy of the particles in a substance. It is a scalar quantity that indicates the degree of hotness or coldness of a body or environment. Temperature is measured using a thermometer, and is usually expressed in degrees Celsius (°C) or Fahrenheit (°F).
3. Absolute zero is the temperature at which a substance has no kinetic energy per particle to give up. It is the lowest possible temperature, and is equivalent to 0 Kelvin (-273.15°C or -459.67°F). At absolute zero, all substances are in a state of minimum energy and motion, and all thermal processes come to a complete stop.
4. Latent heat refers to the energy released or absorbed by a substance during a change of state, such as melting, freezing, boiling, or condensation. Unlike sensible heat, which is associated with changes in temperature, latent heat does not result in a change in temperature, but rather in a change in the physical state of the substance. Latent heat is usually expressed in units of joules or calories per gram.

Understanding the concepts of heat, temperature, absolute zero, and latent heat is important in many areas of science and engineering, including thermodynamics, materials science, and climate science. These concepts are also relevant to our everyday lives, as they help us understand the behavior of the materials and substances around us, and enable us to make informed decisions about energy use and conservation.
