Answer:0.0686 m^3

Explanation:

Given

No of moles=2

T=25^{\circ}\approx 298 K

P_1=210 KPa

T_2=48 ^{\circ}\approx 321 k

P_2=77.7 KPa

PV=nRT

Substitute

77.7\times V_2=2\times 8.314\times 321

V_2=0.0686 m^3

2. the advantage of sexual reproduction is that , it produces genetic variation, disadvantage is it's a very slow process and takes lot of time
3. the advantage is that ,it's a very rapid process as it doesn't involve complex interactions. of genes and chromosomal recombination, the disadvantage would be is that they don't produce variation which can have adverse affect on their survival, even due to slightest change in the environment
4. Undergoing both the type of cell division is good as in human mitotic division is meant for growth and development whereas meiotic divisions are necessary and important for gametes formation and for raising new generation
