Question

The quantity of heat which can rise the temperature of x gm of a substance through t10C can rise the temperature of y gm of water through t20C is same. The ratio of specific heats of the substance to motor is

Answer 1

Answer:

is this question or answer

Answer 2

Given:

Temperature that can rise x = t10C

Temperature that can rise y =  t20C

To Find:

Ratio of specific heats of the substance to motor is

Solution:

For substance x -

ΔQ = ms1 ΔT= x × s1 × t1 --- eq 1

For substance y -

ΔQ = ms2 ΔT= y × s2 × t2 --- eq 2

From equation 1 and 2

x × s1 × t1  = y × s2 × t2

s1/s2 = yt2/xt1 ( Also represents the water equation)

where, s1  is the specific heat of substance  and s2 is the specific heat of water

Answer: The ratio of specific heats of the substance to motor is yt2/xt1
