A helium sample occupies 1.50 L of space at 124.6 kPa. What pressure would the helium need to experience to have a volume of 0.75 L?

A. 130 kPa
B. 97 kPa
C. 250 kPa
D. 62 kPa

Answer : The correct option is, (C) 250 kPa

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,

= initial pressure = 124.6 kPa

= final pressure = ?

= initial volume = 1.50 L

= final volume = 0.75 L

Now put all the given values in the above equation, we get:

Thus, the pressure of helium need to experience to have a volume of 0.75 L would be, 250 kPa

a is the answer to this question

explanation:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
