Answer:
Explanation:
Question 7.
We can use the Combined Gas Laws to solve this question.
a) Data
p₁ = 1.88 atm; p₂ = 2.50 atm
V₁ = 285 mL; V₂ = 435 mL
T₁ = 355 K; T₂ = ?
b) Calculation
Question 8. I
We can use the Ideal Gas Law to solve this question.
pV = nRT
n = m/M
pV = (m/M)RT = mRT/M
a) Data:
p = 4.58 atm
V = 13.0 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
T = 385 K
M = 46.01 g/mol
(b) Calculation
<u>Answer:</u> The amount of CO that is occupied in the room is
<u>Explanation:</u>
We are given:
Concentration of CO = by volume
This means that of CO is present in 1 L of blood
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.99 m
b = breadth of cuboid = 18.97 m
h = height of cuboid = 11.89 m
Converting this into liters, by using conversion factor:
So,
Applying unitary method:
In 1 L of blood, the amount of CO present is
So, in of blood, the amount of CO present will be =
Hence, the amount of CO that is occupied in the room is
Answer:
Latent heat of fusion of the substance is
Explanation:
Latent heat of fusion denotes amount of energy (heat) per unit mass required to melt a solid material at constant temperature and pressure i.e. at it's melting point
Here amount of heat required =
Mass of unknown substance being melted = 18.5 kg
So, latent heat of fusion of the substance = (required heat energy to melt)/(mass of the unknown substance) =
So, latent heat of fusion of the substance is
