Calculate the energy to heat two cubes (silver and copper), each with a volume of 10cm3from 15∘Cto25∘C.

Short Answer

Expert verified

the energy to heat two cubes (silver and copper) is247Jand343Jrespectively.

Step by step solution

01

Given Information Part (1)

The specific heat limit of a substance is the intensity limit of an example of the substance separated by the mass of the example, additionally now and again alluded to as massic heat limit.

We have to find the energy to heat the silver cube.

02

Explanation Part (1)

Given,

The volume of the silver cube = 10cm3

Specific heat = c=0.235J/g0C

Density is role="math" localid="1652064809462" 10.5g

Calculating the mass = density×volume

⇒10×10.5=105g

Temperature change role="math" localid="1652064870615" ΔT=250C−150C=10oC

the energy to heat the silver cube is Q=mcΔT

⇒105×10×0.235=247J

03

Given Information Part (2)

The specific heat limit of a substance is the intensity limit of an example of the substance separated by the mass of the example, additionally now and again alluded to as massic heat limit.

We have to find the energy to heat the copper cube.

04

Explanation Part (2)

Given,

The volume of the copper cube =10cm3

Specific heat =role="math" localid="1652065160103" c=0.385J/g0C

Density is8.92g

Calculating the mass = density× volume

⇒10×8.92=89.2g

Temperature changeΔT=250C−150C=10oC

the energy to heat the silver cube is Q=mcΔT

⇒89.2×10×0.385=343J
