Answer:
=745 Kelvin
Explanation:
- According to the pressure law the relationship between the pressure and absolute temperature of a gas at a constant volume is directly proportional.
- An increase in temperature causes a corresponding increase in pressure at a constant volume.
That is;

Mathematically;

When there are two varying conditions;

In this case;
P1 = 0.8 atm
T1 = 25+273 = 298 K
P2 =2.00 atm
T2= ?
Therefore;



Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
Answer:
T₂ = 43.46 °C
Explanation:
Given that:
The heat of the formation of carbon dioxide = - 393.5 kJ/mol (Negative sign suggests heat loss)
It means that energy released when 1 mole of carbon undergoes combustion = 393.5 kJ = 393500 J
Heat gain by water = Heat lost by the reaction
Thus,
For water:
Mass of water = 5100 g
Specific heat of water = 4.18 J/g°C
T₁ = 25 °C
T₂ = ?
Q = 393500 J
So,
T₂ = 43.46 °C
