V = ( 2.44 x 10⁻² ) x ( 1.4 x 10⁻³ ) x ( 8.4 x 10⁻³ )
V = 2.9 x 10⁻⁷ m³

Answer:
Explanation:
By rearrangement of atoms of reactants. The entire properties will also different from the reactants as the composition changes.
The answer is D. It may gain or lose electrons.
Answer:
The energy required is 3225 Joules.
Explanation:
Given,
mass of lead cube = 500 grams
T₁ = 25°C
T₂ = 75°C
specific heat of lead = 0.129 J/g°C
Energy required to heat the lead can be found by using the formula,
Q = (mass) (ΔT) (Cp)
Here, ΔT = T₂ - T₁ = 75 - 25 = 50
Substituting the values,
Q = (500)(50)(0.129)
Q = 3225 Joules.
Therefore, energy required is 3225 J.
Answer:
cohesive and adhesive forces
Explanation:
The rise or fall of a fluid in a capillary tube is governed by the balance of cohesive and adhesive forces. Inermolecular forces are responsible for cohesion and adhesion. The narrower the bore of a glass tube, the greater the extent of raising or lowering of the liquid.
