Answer: conversion of ice to steam

Explanation: Endothermic process is one in which energy is absorbed by the system.

Conversion of ice to steam is change of solid phase to gaseous phase, thus energy is required to break the strong inter molecular forces of attraction in solids to convert it into gaseous phase.

Conversion of steam to ice, conversion of steam to water  and conversion of water to ice releases energy and are examples of exothermic processes.

Answer:

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

Explanation:

<em>The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.</em>

<u>According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.</u>

In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.

Based on the representation, which of the following statements about the element is true ?
Greeley [361]

We generally represent an element by its symbol. provided with the atomic number and mass number or atomic mass

Atomic number is the number of protons present in an element. It is constant for an element.

The mass number of element is the sum of number of protons and number of neutrons

The atomic mass is the total mass of all the protons and neutrons present in the element (in its nucleus).

the number of electrons is equal to number of protons in a neutral atom of element.

The mass of electrons is not included in the total atomic mass of element as it is very low.

So here

12 = it is the number of protons = atomic number of element.

The true statements are

The combined mass of protons and neutrons is 24.305
