What is the specific heat of an unknown metal of 2.93 kcal of energy are required to raise the temperature of 183.4g sample of the metal by 126.3 Celcius

The specific heat of the unknown metal is 1.26*10⁻⁴

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat occurs when heat added or removed from a substance causes a temperature change in it and is calculated by:

Q = c * m * ΔT

Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT (Tfinal - Tinitial) is the variation in temperature

In this case:

Replacing:

2.93 kcal= c* 183.4 g*126.3 °C

Solving:

c= 1.26*10⁻⁴

The specific heat of the unknown metal is 1.26*10⁻⁴

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
