Answer:
1.36 atm
Explanation:
We'll begin by converting 97 °C to Kelvin temperature. This can be obtained as follow:
T(K) = T(°C) + 273
T(°C) = 97 °C
T(K) = 97 °C + 273
T(K) = 370 K
Finally, we shall determine the pressure in the hot water bottle. This can be obtained as follow:
Volume = constant
Initial temperature (T₁) = stp = 273 K
Initial pressure (P₁) = 1 atm
Final temperature (T₂) = 370 K
Final pressure (P₂) =?
P₁ / T₁ = P₂ / T₂
1 / 273 = P₂ / 370
Cross multiply
273 × P₂ = 370
Divide both side by 273
P₂ = 370 / 273
P₂ = 1.36 atm
Therefore, the pressure in the hot water bottle is 1.36 atm.
