Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

A person is found dead at 5 PM in a room whose temperature is 20 °C. The
temperature of the body is measured to be 25 °C when found, and the heat transfer
coefficient is estimated to be h 8 W/m2 °C. Modeling the body as a 30-cm-diameter,
1.70-m-long cylinder, estimate the time of death of that person. The body can be
modeled as a 30 cm diameter, 1.70-m-long cylinder. The thermal properties and body
temperature of 37 °C.
let The average human body is 72 percent water by mass, and thus
we can assume the body to have the properties of water at the average temperature
of (37 + 25)/2 = 31 °C; k = 0.617 W/m · °C, p= 996 kg/m³, and Cp=4178 J/kg · °C

The outside temperature on a particular winter's day is 0°C. Consider two identical houses, each of external surface area 200 m² and internal temperature 20°C. The walls of the first are constructed of a single layer of brick, of thermal conductivity 1 W m-1 °C-1 and thickness 20 cm. What is the heat flux Q out of this house? What is its rate of heat loss in Watts? The walls of the second house are constructed of two layers of brick, each 10 cm thick, and a layer of insulation, also 10 cm thick. The insulation is made mostly out of air, thermal conductivity 0.01 W m of heat loss from this house?
