Question

How are sensible heat and latent heat different

Answer 1

Sensible heat and latent heat are two different forms of energy involved in heat transfer. Sensible heat causes a temperature change in a substance, while latent heat is the heat energy required or released during a phase change without a temperature change.

Step-by-step explanation:

Sensible heat and latent heat are two different forms of energy involved in heat transfer. Sensible heat refers to the heat energy that causes a temperature change in a substance. It can be measured using the formula Q = mcΔT, where Q is the amount of heat transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

Latent heat, on the other hand, is the heat energy required or released during a phase change without causing a temperature change. It can be measured using the formula Q = mL, where Q is the amount of heat transferred, m is the mass of the substance, and L is the latent heat coefficient.

For example, when water is heated from a solid (ice) to a liquid (water), it absorbs energy in the form of latent heat. Even though the temperature may rise, the latent heat allows the water molecules to break their bonds and become a liquid, without changing the temperature significantly. Sensible heat, on the other hand, is responsible for the temperature change between the solid and liquid states.

Answer 2

• Sensible heat defines the exchange of energy between matters
• Latent heat defines change in internal energy of matters .
• Sensible heat is not related with phase transition
• Latent heat is related to phase transition.
• Senible heat is change in temperature of system whereas latent heat is constant temperature
