Question

8. a. Given that the specific heat of one material is twice that of another compare the amounts of heat required to raise the temperatures of equal masses of each material by 1°C. b. If the same amount of heat were added to samples of both materials and each sample had the same increase in temperature, compare the masses of each sample.

Answer 1

1) Given specific heat of one material ( say A ) is twice than the specific heat of other material ( say B)

Then

Since m_a = m_b ( masses are equal) and temperature rise of 1^oC is given then:

So

2) Given

Then

Given same temperature rise of 1^oC then:

${m_ac_a}={m_bc_b}$
