Answer:
The new volume of the gas is decreased, to 0.329 L
Explanation:
Step 1: Data given
Volume of oxygen = 500 mL = 0.500 L
Pressure = 1.3 atm
Temperature = 25.0 °C
Temperature increases to 29.0 °C
New pressure = 2.0 atm
Step 2: Calculate new volume
p1*V1/T1 = p2*V2/T2
⇒with p1 = the initial pressure = 1.3 atm
⇒with V1 = the initial volume = 0.500L
⇒with T1 = the initial temperature = 25 °C = 298 K
⇒with p2 = the new pressure = 2.0 atm
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the new temperature = 29 °C = 302 K
(1.3 * 0.500)/298 = (2.0 * V2) /302
0.0021812 = 2.0V2 / 302
V2 = 0.329 L = 329 mL
The new volume of the gas is decreased, to 0.329 L
Can you please explain what the BTB is so I may help ya?
Answer:
107,200J or 25.62 kcal
Explanation:
The latent heat of water is 4.2J/g °C so the energy needed to increase the tempearture from 80 °C to 100°C will be:
40g * 4.2J/g °C * (100-80°C )= 3,360J
The heat of vaporization of water is 2260J/g so the energy need to change water from liquid to gas is:
40g * 2260J/g = 90,400J
The heat needed to increase steam temperature should be same as latent heat of water, 4.2J/g °C . So, the energy needed to increase temeprature from 100 to 180 will be:
40g * 4.2J/g °C * (180-100°C )= 13,440J
The total energy needed will be: 3,360J + 90,400J +13,440J= 107,200J
