The amount of heat required that is used to change 1l of water into vapour at atmospheric pressure is known as latent heat of vaporisation
Answer:
ρ = 0.5 g/cm³
Explanation:
Step 1: Given data
Volume of the block of wood (V): 8.0 cm³
Mass of the block of wood (m): 4.0 g
Density of the block of wood (ρ): ?
Step 2: Calculate the density of the block of wood
The density of the block of wood is equal to its mass divided by its volume. The mathematical expression is:
ρ = m/V
ρ = 4.0 g/8.0 cm³
ρ = 0.5 g/cm³
It is , how close a measurement is to an accepted value for the measurement !
