the kinetic energy always increases whether the temperature increases or decreases
the total kinetic energy of the molecules is not affected by a change in temperature
as the kinetic energy of the molecules decreases, the temperature increases
Answers
Answer: as the temperature increases, the kinetic energy of the molecules increases
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.
where T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
The production of the energy by the moving particle is called kinetic energy. The kinetic energydepends on the following:-
- Mass
- Velocity
The kinetic energy of every state is different i.e the kinetic energy of the solid, liquid, and gas are different. The kinetic energy of the particles is directly proportional to the temperature of the gas.
T= temperature
R= gas constant
Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
Hence, the correct option is A

The pressure inside the flask on heating it is given as 1.21 atm.
Explanation:
As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.
So P ∝ T
To convert celsius to kelvin, add 273.15 to the temperature value in celsius
Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as
So, the pressure inside the flask on heating it is given as 1.21 atm.
Final answer:
Using Gay-Lussac's law, the final pressure of the gas in the flask after heating from 24°C to 104°C, under a constant volume, is approximately 1.2 atm.
Explanation:
The pressure inside the flask can be calculated by using Gay-Lussac's law, which states that the pressure of a gas is directly proportional to its absolute temperature, as long as volume is constant. This is formally expressed as P1/T1 = P2/T2, where P is pressure, T is absolute temperature (in Kelvin), and the subscripts refer to initial and final states.
First, convert the Celsius temperatures to Kelvin by adding 273.15 to the Celsius temperature. T1 = 24°C + 273.15 = 297.15 K, and T2 = 104°C + 273.15 = 377.15 K. Next, rearrange the equation to solve for P2: P2 = P1 (T2 / T1).
So, P2 = 0.95 atm * (377.15 K / 297.15 K) ≈ 1.2 atm. Therefore, the pressure inside the glass laboratory flask after heating to 104°C would be approximately 1.2 atm.
