Explanation:
When water is boiled in the flask . Some portion of it is evaporated out . Now when cork is placed on it and is placed in the ice box . It cools down , by which the pressure inside decreases .
Due to decrease of pressure , the boiling point of water also decreases . Now it can boil at lower temperature . Thus it starts boiling at lower temperature even , when placed in the ice box .
Answer:
In an elastic collision, the momentum is conserved and the mechanical energy is conserved too.
Explanation:
There are two types of collisions:
- Elastic collision: in an elastic collision, the total momentum before and after the collision is conserved; also, the total mechanical energy before and after the collision is conserved.
- Inelastic collision: in an inelastic collision, the total momentum before and after the colllision is conserved, while the total mechanical energy is not conserved (in fact, part of the energy is converted into other forms of energy such that thermal energy, due to the presence of frictional forces)
Answer:
The scientist finds an equation that predicts how long the rainstrom will last.
Explanation:
I just answered it :)
Answer:
The correct option is: A) As Earth goes around the Sun and Earth's axis remains pointed toward Polaris, the Northern and Southern hemispheres alternately receive more and less direct sunlight.
Explanation:
Seasons on Earth are the changes in the weather caused due to the <u>titled axis of the Earth, relative to the orbital or ecliptic plane</u>, while orbiting around the Sun. The Earth's axis of rotation is<u> tilted approximately by an angle of 23.4°. </u>
This results in the change in the intensity of the sunlight received by the Earth's surface, due to which the southern and the northern hemispheres <u>experience opposite seasons.</u>
The average kinetic energy of the gas would also be constant since the temperature of the gas is not changing.
<h3>What happens to the average kinetic energy?</h3>
The kinetic energy is the energy of the particle that is motion. We know that the kinetic energy of the gas is proportional to the temperature of the gas. As the temperature increases, the kinetic energy of the particles of the gas increases.
Now we can see that the gas has been maintained at a constant temperature and a constant volume and that the particles of the gas collide with each other. This implies that the average kinetic energy of the gas would also be constant since the temperature of the gas is not changing.
