Question

Two pieces of metal with exactly the same mass are placed on a surface in bright sunlight. The temperature of the 1st block increases by 3°C while the temperature of the 2nd increases by 8°C. If the specific heat of the 2nd block is 0.24 J/g-K, what is the specific heat of the 1st block?

Answer 1

B. 0.64 J/g-K I already did the test this was the correct answer

Answer 2

Answer:The specific heat of the first block is 0.64 J/gK,

Step-by-step explanation:

Block-2

`Q= m* c* \Delta T`

Q= heat from the sun

m = mass of the block-2

c = heat capacity of block-2= 0.24 J/g K

`\Delta T={\text{Change in temperature}}=8^oC`

`Q=m* c* 8^C`..(1)

Block-1

Q= heat from the sun

m = mass of the block-2

c' = heat capacity of block-1

`\Delta T'={\text{Change in temperature}}=3^oC`

`Q=m* c'* 3^oC`..(2)

Dividing(1) by (2)

`(Q)/(Q)=(m* 0.24 J/gK* 8oC)/(m* c'* 3^oC)`

c'= 0.64 J/gK

he specific heat of the first block is 0.64 J/gK,
