Why does the temperature not change
S_A_V [24]

Answer:

Option A

Explanation:

Temperature of a body is due to the heat gained or loss. During a phase change, the atoms or molecules of a substance are undergoing change is temperature due to which no temperature change is observed during phase change. The heat in the transition phase is used to break bonds and the change in temperature is felt when kinetic energy change is complete. During transition, the average kinetic energy of the molecules remains unchanged and hence during a phase change a temperature do not changes until unless the phase change is completed.

Hence, option A is correct

____ [38]

Atoms with the same number of protons but different masses are called Isotopes.

<h3>What are Isotopes?</h3>

An isotope is one of two or more chemical elements that exist in different forms. Varied isotopes of an element have the same atomic number and protons in their nuclei, giving them the same atomic weight. However, each elemental isotope has a different amount of neutrons, which changes its atomic weight.

isobars - Isobars are atoms (nuclides) of several chemical elements that have diverse chemical characteristics but share the same physical characteristics. So, we may define isobars as elements with the same mass number but a different atomic number.
