A system of weight 7 Kg is heated from its initial temperature of 10°C to its final temperature of 30ºC. Find out the total heat obtained by the system. Note that the specific heat of the system is 0.45 kJ per Kg K. 18. The color orange within the visible light spectrum has a wavelength of about 620 nanometers or 620 x10 meters and the speed of light waves is a constant value of 3.0x10•m/s. What is the frequency of orange light?

Two 0.525-m rods, one lead and the other copper, are connected between metal plates held at 2.00 °C and 106 °C. Therods have a square cross section, 1.50 cm on a side. How much heat flows through the two rods in 1.00 s? Assume thatno heat is exchanged between the rods and the surroundings, except at the ends.

Water at 100 psig is flowing inside a 2 in sch 40 pipe (D₁ = 0.1723 ft) at a rate of 25 lb/s, then it flows through an additional pipe of 1 in sch 40 (D2 = 0.0874 ft) and leaves this second pipe at 40 psig at an elevation 20 feet above the inlet to the large pipe. No pump is used in the set- up. The net heat imparted from the surrounding is 1500 BTU/hr. Calculate the total friction expressed in lbf-ft/lb.
