Two solid objects, a and b, are placed in boiling water and allowed to come to temperature there. each is then lifted out and placed in separate beakers containing 1000 g of water at 10.0 ºc. object a increases the water temperature by 3.5 ºc; b increases the water temperature by 2.6 ºc. which has the larger specific heat?

Given:

Mass of object 'a' = Mass of object 'b' = 1000 g

Initial temperature of water T1 = 10 C

Increase in water temperature due to 'a' = 3.5 C

Increase in water temperature due to 'b' = 2.6 C

To determine:

If object 'a' or 'b' has the larger specific heat  

Explanation:

Heat (Q) involved in a chemical reaction is given as-

Q = mcΔT= mc(T2-T1) (1)

where m = mass

c = specific heat

ΔT = change in temperature

Now the specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by 1 C.

c = Q/mΔT

Based on the above equation, for substances of equal masses, lower the ΔT value higher will be the specific heat.

For object a, ΔT = 3.5 C and for object b, ΔT = 2.6 C.

Hence b will have a higher specific heat.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.
