Answer:
C. Replacing one gas by another under the same conditions, has no effect on pressure.
Explanation:
Ideal gas:
A gas is treated as an ideal gas if temperature is high and pressure is low.
Kinetic energy for ideal gas given as

So when temperature of gas is increases then Average molecular kinetic energy will also increases.
The size of molecule is negligible as compare to the dimension of container. It mean that volume occupied by molecule is less as compare to the volume of container.
The between molecules is perfectly elastic.
Ideal gas equation
P V = m R T
So the option C is not always true.
Answer:
True
Explanation:
an object in motion stays in motion unless acted upon by another force
The correct answer is option (c) i.e. Energy will be converted into another form.
<span>
During a chemical reaction, energy remains unchanged, It just gets converted into another form and doesn’t increases or decreases. Excess energy is released in the form of heat, light during a chemical reaction and thus, proving the law of conservation of energy which says, energy can neither be created nor destroyed. It just gets converted from one form to another form. </span>
Rotational kinetic energy = Iω²/2 = 10
I = rotational inertia(moment of inertia)
ω= angular speed = 10 s⁻¹
∴ 10 = I(10²)/2
∴ I = 20/10² = 0.2 kg-m²
