100g of ice at 0°C is mixed with 100g of water at 80°C

$\mathop {at\,0^\circ C}\limits^{ice} \to \mathop {at\,0^\circ C}\limits^{water} \to \mathop {at\,6^\circ C}\limits^{water}$

At equilibrium, heat released by 100gm of water = heat absorbed by 100gm of ice i.e.m₁c₁ (80 - 6) = m₂ L + m₂c₁(6 - 0)[c₁, m₁, m₂ and L are specific heat of water, mass of water, mass of ice and latent heat of fusion of ice respectively.)
$\therefore$ 100 × 1 × 74 = 100 L + 100 × 1 × 6

$\Rightarrow$ L = (1 × 74) -6
$\Rightarrow$ L = 68 cal/gm

This is the required value of latent heat of fusion of ice.

Preeti Dabral 2 years, 3 months ago

In the steady-state,
Rate of flow of heat through cube A
= Rate of flow of heat through cube B.
or $\frac{K_{1} A(100-T)}{x}=\frac{K_{2} A(T-0)}{x}$
or $\frac{300 A(100-T)}{x}=\frac{200 A(T-0)}{x}$
or 300 - 3T = 2T or 5T = 300
T = 60°C

Derive en expenssion of time period of simple pendulam

Posted by Harshita Narware 2 years, 3 months ago

Preeti Dabral 2 years, 3 months ago

Time period T= time required to complete one oscillation.

At equilibrium T₀=mg.

For small displacement θ

Restoring force =−mgsinθ

for small θ sinθ≈θ

$\begin{aligned} & \Rightarrow \mathrm{fe}=-\operatorname{mg} \theta=-\mathrm{mg}\left(\frac{\mathrm{x}}{\mathrm{l}}\right) \\ & \text { acceleration } \mathrm{a}=\frac{\mathrm{fe}}{\mathrm{m}}=\frac{-\mathrm{g}}{1} \cdot \mathrm{x} \end{aligned}$

We know for SHM, a=−w²x

$\begin{aligned} & \Rightarrow \text { On comparing we get } \mathrm{w}=\sqrt{\frac{\mathrm{g}}{\mathrm{l}}} \\ & \therefore \text { Time period of oscillation } \mathrm{T}=\frac{2 \Pi}{\mathrm{w}}=2 \Pi \sqrt{\frac{1}{\mathrm{~g}}} \end{aligned}$

Plot graph between heat supplied versus temperature showing latent heat of fusion and latent heat of vaporization

Posted by Sejal Kumari 2 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Preeti Dabral 2 years, 3 months ago

Latent Heat

When a substance adjustments phase, this is it is going from both a strong to a liquid or liquid to gas, the strength, calls for strength to do so. The potential energy withinside the interatomic forces among molecules desires to be conquered with the aid of using the kinetic strength of the movement of the particles earlier than the substance can change phase.

Latent Heat of Fusion and Vaporization

The strength required to extrude the section of a substance is referred to as latent heat. The phrase latent means were hidden. When the phase extrudes is from strong to liquid we ought to use the latent warmth of fusion, and whilst the phase extrude is from liquid to a gas, we ought to use the latent warmth of vaporization.

To initiate a phase change and whole it, a little energy withinside the form of heat is required. This heat is referred to as latent heat. Thus all of the energy provided all through this phase may be applied best for the phase change method and now no longer for increasing the temperature. Thus all through the discharge of latent heat, the temperature stays constant.
