B is correct answers because metal have less reactive
Answer:
20.2 °C
Explanation:
When the pressure and number of moles are constant, Charles's law may be used to solve for temperature:
T₁/V₁ = T₂/V₂ >> T₂ = T₁ (V₂/V₁)
Expressions for the volumes can be substituted and simplified:
T₂ = T₁ (V₂/V₁) = T₁ (4/3πr₂³/4/3πr₁³) = T₁ (r₂³/r₁³)
Substituting in values in the equation (where the radius r is half of the diameter) gives:
T₂ = T₁ (r₂³/r₁³) = (19.0°C) x ((51.0cm/2)³/(50.0cm/2)³) = 20.2 °C
Solid: vibrating at fixed position, because they have a strong force of attraction
Liquid: molecules sliding over each other, because they have a weaker force of attraction than solids
Gas: molecules moving freely at random directions, because they almost have no force of attraction
Answer:
Volume also reduced to half
Explanation:
Volume and absolute temperature are directly proportional to each others
