The pressure inside a pressure cooker is set to be 1054 g/cm.
You are given that
1 kg = 2.205 pounds
1 cm = 0.3937 inches
Work out the pressure inside the pressure cooker in pounds per square inch.
Give your answer correct to 2 decimal places.
Answer is in a photo. I couldn't attach it here, but I uploaded it to a file hosting. link below! Good Luck!
D. A syringe pulls in air as the plunger is pulled back.
As per Charles’s law
At constant pressure for a given amount of a gas,
Volume is directly proportional to its temperature.
Directly proportional means when one increases the other one too will increase. That is when volume increases temperature too will increase. When volume decreases, temperature too will show a decrease.
Option A tells us that the volume of the hot air balloon increase due to the rise(increase) in temperature as the balloon is heated
Thus the expression is
where k is a constant
When there is a change in the volume and temperature the expression will be
where and are the initial volume and initial temperature and and are the final volume and temperature.
The Charles law states that the volume of an ideal gas increases when temperature is increased under constant pressure. The pressure inside the balloon is always equal to the atmospheric pressure. Therefore answer A demonstrate the Charles law.
Here's link to the answer:
time taken to cook on the pressure cooker = 100 seconds = 1.67 mins
1 kg = 2.205...
