(Triple points) A scientist found that a sample of metal expands from 26.1 cm3 to 26.2 cm3 when heated from 25 °C to 75 °C. What would the coefficient of volume expansion be for this metal?

7.66×10⁻⁵ K⁻¹

Explanation:

From the question,

γ = (v₂-v₁)/[v₁(t₂-t₁)] Equation 1

Where γ = coefficient of volume expansion, v₁ = initial volume, v₂ = Final volume, t₁ = initial temperature, t₂ = Final Temperature.

Given: v₁ = 26.1 cm³, v₂ = 26.2 cm³, t₁ = 25 °C, t₂ = 75 °C.

Substitute these values into equation 1

γ = (26.2-26.1)/[26.1(75-25)]

γ = 0.1/(26.1×50)

γ = 0.1/1305

γ = 7.66×10⁻⁵ K⁻¹

Hence the coefficient of volume expansion is 7.66×10⁻⁵ K⁻¹

explanation:

newton's third law, for every action there is an equal and opposite reaction.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
