Answer:
P₂ = 1.03 atm 
Step-by-step explanation:
Given data:
Initial pressure = 1.00 atm
Initial temperature = 293 K
Final temperature = 303 K
Final pressure = ?
Solution:
According to Gay-Lussac Law, 
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles. 
Mathematical relationship: 
P₁/T₁ = P₂/T₂ 
Now we will put the values in formula: 
1.00 atm / 293 K = P₂/303 K 
P₂ = 1.00 atm × 303 K / 293 K 
P₂ = 303 atm. K /293 K 
P₂ = 1.03 atm
