The volume of gas under STP is 0.512 liters.
<u>Explanation:</u>
At STP (Standaed Temperature and Pressure)
T = 0°C
P = 1 atm = 760 mmHg
Given
P1 = 756 mmHg
T1 = -21.5°C = -21.5 + 273 = 251.5 K
V1 = 475 mL = 0.475 L
P2 = 760 mmHg
T1 = 0°C = 0 + 273 = 273 K
We know that
V2 = 0.512 L
Answer:
Kinetic energy is the energy in a moving object, such as a person that has already jumped. Potential energy means energy that could be used. A bouncy ball sitting on a shelf 5 ft from the ground has less potential energy than one sitting 10 ft from the ground. A person that is about to bungee jump has potential energy because they are not yet in motion.
