Suppose you apply a flame to heat 1 liter of water and its temperature rises by 3 C. If you apply the same flame for the same length of time to 3 liter of water, by now how much does its temperature rise

Answer :

Answer:1[tex]^{0}C[/tex]

Explanation:

Let the heat given by flame be [tex]h[/tex].

Let [tex]m_{1}[/tex] be the mass of water in case 1.

Let [tex]m_{2}[/tex] be the mass of water in case 2.

Let Δ[tex]T_{1}[/tex] be the temperature difference in case 1.

Let Δ[tex]T_{2}[/tex] be the temperature difference in case 2.

Let [tex]V_{1}[/tex] be the volume of water in case 1.

Let [tex]V_{2}[/tex] be the volume of water in case 2.

Let [tex]d[/tex] be the density of water.

Let [tex]s[/tex] be the specific heat of water.

Given,

[tex]V_{1}=1L\\V_{2}=3L\\[/tex]

Δ[tex]T_{1}=3^{0}C[/tex]

Since the same heat is given to water in both the cases,

[tex]h=m_{1}s[/tex]Δ[tex]T_{1}[/tex]

[tex]h=m_{2}s[/tex]Δ[tex]T_{2}[/tex]

So,[tex]m_{1}s[/tex]Δ[tex]T_{1}[/tex]=[tex]m_{2}s[/tex]Δ[tex]T_{2}[/tex]

Since mass is product of volume an density,

[tex]V_{1}ds[/tex]Δ[tex]T_{1}[/tex]=[tex]V_{2}ds[/tex]Δ[tex]T_{2}[/tex]

[tex]1\times d\times s\times 3=3\times d\times s\times[/tex]Δ[tex]T_{2}[/tex]

So,Δ[tex]T_{2}=1^{0}C[/tex]
