A sample of hydrogen exerts a pressure of 1.50 atmospheres at a temperature of 160 K. What pressure does the gas exert at 640 K?
The pressure will be
The volume is not given, so I assume it remains unchanged.
To calculate the new pressure you use the following equality:
So here we have:
We can divide both sides of the equation by
From this proportion we calculate that:
If we substitute the given values we get:
Answer: The new pressure is
