Answer:
The pressure inside the bottle is 92.678 atm.
Explanation:
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
×××
In this case:
P= ?
V= 500 mL= 0.500 L
n= 60 g* = 2.07 moles
R= 0.082
T= 0 C= 273 K
Replacing:
P* 0.500 L= 2.07 moles* 0.082 * 273 K
Solving:
P= 92.678 atm
The pressure inside the bottle is 92.678 atm.

Answer:</h3>
259,000 Joules
<h3>
Explanation:</h3>
To calculate the heat energy needed to change 100 grams of liquid water at 75°C to vapor at 225°C, we will do this in steps;
<h3>
Step 1: Heat energy required to raise the temp of water from 75°C to 100°C</h3>
Mass of water = 100 g
Heat capacity of water = 4.184J/g °C
Temperature change (75°C to 100°C) = 25°C
Using the formula to get Quantity of heat;
Q = mcΔT
= 100 g × 4.184 J/g °C × 25°C
= 10,460 joules
<h3>
Step 2: Heat required to change water at 100°C to vapor at 100°C</h3>
Mass of water = 100 g
Heat of vaporization = 2,256 J/g
Heat required to change water to vapor without a change in temperature is given by;
Q = m × Lv
= 100 × 2,256 J/g
= 225,600 Joules
<h3>
Step 3: Heat energy required to raise the temperature of ice from 100°C to 225°C.</h3>
Mass of vapor = 100 g
Specific heat of gas = 1.84 J/g °C
Change in temperature (100°C to 225°C) = 125°C
Therefore;
Q = mcΔT
= 100 g × 1.84 J/g °C × 125°C
= 23,000 joules
<h3>Step 4: Total heat energy required</h3>
Total energy = 10,460 J + 225,600 J + 23,000 J
= 259,060 J
= 259,000 J(approx)
Therefore, heat energy required is 259,000 Joules
