At constant pressure, 492 ml of a gas at 31.00c is heated and the volume expands to 876ml. what is the new temperature in kelvin?
a) 171 k
b) 291 k
c) 328 k
d) 541 k

Option (D) is the correct answer.

Explanation:

It is given that pressure is constant and the given data is as follows.

          = 492 mL,             = 31 + 273 = 304 K

          = 876 mL,           = ?

Therefore, calculate the temperature as follows.

Since pressure is constant so, value of P = 1.

                         =

                         = 541.268 K

                         = 541 K (approx)

Thus, we can conclude that value of is 541 K.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
