Answer:
relative humidity
Explanation:
Relative humidity can be measured with a hygrometer
Answer:
The temperature is 69.05 K.
Explanation:
We have,
Number of moles are 6
Pressure is 3.4 atm and a volume of 10 liters.
It is required to find the temperature. It can be calculated using gas law equation. It says that,
P is pressure
V is volume
n is number of moles
R is gas constant, 
T is temperature
Plugging all the values we get :
So, the temperature is 69.05 K.
The answer is B as isotopes are different versions of the same chemical element containing the same amount of protons and electrons but different amounts of neutrons.
