Question

a container having temperature 57°C having pressure P what will the pressure if the temperature is 127°C ?​

Answer 1

Answer:

Correct option is

C

4

3

PV = nRT = constant

Here Pressure P and Volume V are constant in this case,

n is number of moles

R is gas constant

T is temperature

Given temperatures are 27 and 127 degree celcius

T

1

= 27 + 273 = 300 K

T

2

= 127 + 273 = 400 K

So,

n

1

T

1

= n

2

T

2

n

×300 = n

2

×400

n

So the fraction of the original amount of the gas escaped is 3/4

Answer 2

Answer:

C is Correct answer

Explainiation: - PV = nRT = constant

Here Pressure P and Volume V are constant in this case,

n is number of moles

R is gas constant

T is temperature

Given temperatures are 27 and 127 degree celcius

T1 = 27 + 273 = 300 K

T2 = 127 + 273 = 400 K

So,

n1 T1 = n2 T2

n1×300 = n2×400 

n2= 43n1

So the fraction of the original amount of the gas escaped is 3/4
