Substance A would have a delta T (change in temp) rise 1/2 the rise in substance B.

Q=mc x delta T

Q= heat energy in Joules
m= mass of substance heated or cooled
c= specific heat
ΔT is change in temp.

Solve for change in temp=. Q/mc

Specific heat and mass are not inversely proportional to heat energy input.

Putting into real world scenario of using water to heat a building.

Specific heat of water is 1.
It takes 1 btu to raise one pound of water 1 degF. at a base of 60 degF

Acetone specific heat is .51

So it takes half the amount of heat input to get a 100 degree ΔT, as compared to water.

Use this technique to find a formula for the intensity I of a sound, in terms of the sound level β and the reference intensity I
denis23 [38]

Answer:

I = I_o (10^{\frac{\beta}{10}})

Explanation:

As we know that sound level is given as

\beta = 10 Log (\frac{I}{I_o})

so here we have

\frac{\beta}{10} = Log(\frac{I}{I_o})

now we can take anti log both sides

10^{\frac{\beta}{10}} = \frac{I}{I_o}

so we have

I = I_o (10^{\frac{\beta}{10}})

so above is the expression for the intensity of sound in terms of reference intensity and sound level
