What is the dimension of heat?

ML2T−2.

What is the dimension of temp and heat?

[ML2T2K−1]

What is the formula and unit of heat?

In SI units, heat capacity is expressed in units of joules per kelvin (J/K). An object’s heat capacity (symbol C) is defined as the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object. C=QΔT. C = Q Δ T .

What is the formula of heat produced?

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating.

What are the 3 formulas of heat?

Different formulas for Heat

• H = (VI)t.
• H = (I 2 R)t.
• H = (V 2 /R)t.

What is the formula of heat current?

What are the 3 formulas for heat?

The Heat formula is:

• C = \frac{Q}{m\Delta T} Where,
• Specific heat of iron, C = 0.45 Jg^-1°C. Also, temperature difference,
• \Delta T = 700° C – 250° C.
• \Delta T = 450° C. Now applying the heat formula,
• c = \frac{Q}{m\Delta T} rearranging the formula.
• Q = mc\Delta T.
• Q = 1 \times 0.45 \times 10^3 \times 450. = 20.25 J.
• Q.

What is the formula for Joules law of heating?

Joule’s Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow). Or, written differently, H (Heat) = I2 (Current squared) x R (Resistance) x T (Time the current is allowed to flow).

What is the dimensional formula of heat energy?

Since, the dimensions of Heat Energy = Dimensions of Work Done And, Work = Force × displacement = M × a × displacement = [M] × [M 0 L 1 T -2] × [L] ∴ the dimensional formula of Heat energy = M 1 L 2 T -2….

How do you find the dimensional formula of latent heat?

Dimensional Formula of Latent Heat. The dimensional formula of latent heat is given by, [M 0 L 2 T-2] Where, M = Mass; L = Length; T = Time; Derivation. Latent heat (L) = Heat × [Mass]-1. . . . . . (1) The dimensional formula of mass = [M 1 L 0 T 0] . . . . (2) Also, the dimensions of heat = dimensions of energy = dimensions of work

What is the dimension of latlatent heat?

Latent heat (L) = Heat × [Mass] -1 Or, L = [M 1 L 2 T -2] × [M 1 L 0 T 0] -1 = [M 0 L 2 T -2 ]. Therefore, latent heat is dimensionally represented as [M0 L2 T-2]. ⇒ Check Other Dimensional Formulas:

What is the dimension of heat energy in MCQs?

Work = [M 1 L 1 T -2] × [M 0 L 1 T 0 ] = [M 1 L 2 T -2 ]. Therefore, heat energy is dimensionally represented as [M1 L2 T-2]. Put your understanding of this concept to test by answering a few MCQs.
