How does increasing and decreasing the temperature affect the kinetic energy of molecules? How does this impact heat

1 answer:

3 0

Answer: As the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.

Explanation:

James Clerk Maxwell developed the kinetic-molecular theory (KMT) of gases. In this theoey, five assumptions concerning an ideal gas was made. One of the them was that," the average kinetic energy of the gas molecules is proportional to the temperature of the gas". This simply means that a s the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.

Also another scientist known as Rudolf Clausius incorporated energy into the kinetic theory. He proposed that heat is a form of energy that affects the temperature of matter by changing the motion of molecules in matter.

Heat is defined as the flow of energy which is caused by difference in temperature.

In conclusion, when the temperature of a system is increased, the collision of the molecules with one another and the walls of their container increases as more molecules gain more heat energy at higher temperature. While as the temperature of the system decreases, the collision of the molecules will also decrease as molecules lose heat energy at lower temperature.

ЗKOH + H3PO4=K3PO4 + 3H2O <br> what is the reaction

pentagon [3]

Answer: The given reaction is a neutralization reaction.

Explanation:

When an acid chemically reacts with a base then it leads to the formation of salt and water.

For example, $3KOH + H_{3}PO_{4} \rightarrow K_{3}PO_{4} + 3H_{2}O$

Here, KOH is a the base and $H_{3}PO_{4}$ is an acid which on chemical reaction with each other leads to the formation of salt $(K_{3}PO_{4})$ and water $(H_{2}O)$ .

Thus, we can conclude that the given reaction is a neutralization reaction.

The boiling point of a substance is tested. After 10 tests, the result is given as 37+/−3°C. Which conclusion can be drawn from

kenny6666 [7]

From the data obtained from the tests, the actual boiling point lies between 34°C and 40°C.

The boiling point of a substance is the temperature at which the pressure of the substance becomes equal to atmospheric pressure. Pure substances have a sharp boiling point while impure substances boil over a temperature range.

In this case, the boiling point of the substance after 10 tests is obtained as 37+/−3°C. This implies that the actual boiling point lies between 34°C and 40°C.

The energy of a nuclear reactor gets converted to electricity by using steam. As steam converts mechanical energy to electricity.

Answer: Option C

<u>Explanation: </u>

Nuclear reaction works on the principle of nuclear fission. The main functioning of nuclear reactor is the generation of neutrons by fission of Uranium oxide.

The rate of generation of neutrons need to be controlled in the reaction to have a controlled chain reaction which is suitable for generating electricity.

So, the controlling of rate of nuclear generation is done by moderators. The moderators are generally water or graphite in any nuclear reactor. So during these process, steam is produced in the reactor core which then flows through a turbine engine.

The steam rotates the turbines in the generator and thus the mechanical energy of the turbine during rotation is converted as the electrical energy in the generator.

Set up a ripple tank with a wave generator on one side.

Simora [160]

when the waves pass from the deeper water to the shallower water its speed will decrease.

<h3>What is refraction of wave?</h3>

Refraction of wave is the change in direction of a wave passing from one medium to another caused by its change in speed.

For example, waves travel faster in deep water than in shallower water.

Thus, we can conclude that when the waves pass from the deeper water to the shallower water its speed will decrease.
