Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.
Answer:
The pressure inside the bottle is 92.678 atm.
Explanation:
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
×××
In this case:
P= ?
V= 500 mL= 0.500 L
n= 60 g* = 2.07 moles
R= 0.082
T= 0 C= 273 K
Replacing:
P* 0.500 L= 2.07 moles* 0.082 * 273 K
Solving:
P= 92.678 atm
The pressure inside the bottle is 92.678 atm.
Answer:
A. Water changes from a gas to a liquid to a solid.
Explanation:
We can see the following points in the diagram:
- Point A: water starts at 0.5 atm and 100°C, so it is vapor (gas).
- Point B: water changes from vapor to liquid.
- Point C: water changes from liquid to solid.
- Point D: water as a solid reaches a temperature of -10°C.
So, water changes from a gas to a liquid to a solid.
Answer:
Vitamin D
Explanation:
Without Vitamin D animals (humans included) will start to degrade and organs will shut down
The probability that the resulting offspring will be tall in ratio is 1:2:1
