Question

A certain amount of heat q will warm 1g of material x by 3 degrees and one gram of material y by 4 degrees. Which has more specific heat capacity

Answer 1

Specific heat of x will be more than specific heat of y

Explanation:

Let the specific heat capacity of x is $c_x$ and specific heat capacity of y is $c_y$

Amount of heat is given Q

Change in temperature of material x is 3°C

And change in temperature of material y is 4°C

Amount of heat is given by

$Q=mc\Delta T$

For material x

$q=1\times c_x\times 3$

$Q=3c_x$------eqn 1

For material y

$q=1\times c_y\times 4$

$q=4c_y$-----eqn 2

From equation 1 and 2

$3c_x=4c_y$

$c_x=\frac{4}{3}c_y$

So specific heat of x will be more than specific heat of y

Answer 2

Answer:

Material X

Explanation:

Specific heat capacity = Heat / Mass * Change in temp

for material x:
q/1*3 = q/3

for material y:
q/1*4 = q/4

We can clearly see
q/3 > q/4

Hence, Material X has higher specific heat capacity
