In a room with a temperature of 20°C, a metal rod with one end at 100°C is placed. Calculate the temperature at the other end of the rod after 10 minutes if the thermal conductivity is 150 W/m·K.
💡 Hint: Consider the heat flow equation and how it varies with time.
A hot water tank loses heat due to convection and radiation. If the surface temperature of the tank is 80°C and the surroundings are at 20°C, calculate the heat loss rate using Newton’s Law of Cooling and Stefan-Boltzmann Law.
💡 Hint: Break it down into the two parts: convection and radiation per their respective laws.
