Answer:
the answer wold be 10.129
Step-by-step explanation:
To solve hg = 45g
Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.
hg (1/g) = 45g (1/g)
h = 45
Or you can divide both sides with the equation with g.
hg / g = 45g / g
You can cancel g to both sides.
Then,
h = 45
Answer:
V₂ = 252 cm³
Step-by-step explanation:
Charles's law = If the pressure is held constant, the volume of a gas varies directly with the temperature measured on the Kelvin scale.
Mathematically, 

We have, V₁ = 192 cm³, T₁ = 112 K, T₂ = 147 cm³, V₂ = ?
Using the above relation of Charles's law :

So, the new temperature is 252 cm³.
