Answer:
is the volume of the air in the balloon after it is heated.
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
(at constant pressure)
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
is the volume of the air in the balloon after it is heated.
Answer:
Explanation:
An object decreases in size due to the collision of materials. An object increases in size due to the addition of materials. Gas particles are formed from solar nebula materials.
Answer:
ρ = 7.9 g/mL
Explanation:
The total volume (21.36 mL) is equal to the sum of the volume of iron and the volume of water.
V = V(water) + V(iron)
V(iron) = V - V(water)
V(iron) = 21.36 mL - 20.10 mL
V(iron) = 1.26 mL
9.9 grams of iron occupy a volume of 1.26 mL. The density (ρ) of iron is equal to its mass (m) divided by its volume (V).
ρ = m/V
ρ = 9.9 g / 1.26 mL
ρ = 7.9 g/mL
