Answer: 4.10 liters
Explanation:
Given that:
initial volume of gas V1 = 3.0L
initial temperature of gas T1 = 273K
new volume V2 = ?
new temperature T2 = 373K
Since, only volume and temperature are involved, apply the formula for Charle's law
V1/T1 = V2/T2
3.0L/273K = V2/373K
To get the value of Z, cross multiply
3.0L x 373K = 273K x V2
1119 = 273V2
Divide both sides by 273
1119/273 = 273V2/273
4.10L = V2
Thus, the new volume is 4.10 liters
Answer:
Q = 217.63J
Explanation:
Data;
Mass = 34.5g
T1 = 26.4°C
T2 = 75.3°C
c = 0.129J/g°C
Energy (Q) = mc(T2 - T1)
Q = 34.5 * 0.129 *(75.3 - 26.4)
Q = 4.4505 * 48.9
Q = 217.629J
Q = 217.63J
The heat gained was 217.63J
Answer: Thermal Energy
Explanation:
Thermal Energy is for anything that relates to heat, so a hairdryer also uses thermal energy
