Step-by-step explanation:
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.
Answer:
Grams
Step-by-step explanation:
Mass is the amount of matter present inside a solid. Kilograms and grams are the units to measure mass of an object.
For pencil, the unit to measure its mass is grams. As its mass is less, we can use smaller unit.
Hence, the correct option is (c) "grams"
