Answer:
Convection
Explanation:
Hot water will rise due to heat transfer by convection occurring in the heating system.
- When a fluid is heated, the molecules will gain thermal energy.
- As the thermal energy of the liquid increases, the molecules will have heat which is average kinetic energy in the system.
- This causes them to be less denser and they rise in the cooking medium.
- As they rise, the colder part of the water sinks down to replace them in the pot.
- This exchange sets up convection cells in the heating medium.
Answer:
<h2>7.54 atm </h2>
Explanation:
The required pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>7.54 atm </h3>

Answer:
When we shake the branch of a tree the tree possesses a state of motion whereas the fruits and leaves tend to remain in state of rest. Due to this inertia of rest the fruits and leaves get detached from the branch and because of gravity it falls down.
Explanation:
so it's because of the gravity .
Do you have choices??????????????????
