(ii) If the temperature of any object is 83.12°F then calculate its value in °C (a) – 18.88 (b) 28.4 (c) 271 (d) - 16.67

(b) Temperature data compiled since the 1950s indicate that the troposphere has warmed by 0.14°C per decade, and that the lower stratosphere has cooled by as much as 0.20°C per decade. Express these temperature changes in degrees  Fahrenheit

(1b). A wood stove is used to heat a single room. The stove is cylindrical in shape, with a diameter of 34 cm and a length of 64 cm, and operates at a temperature of 460°F. If the temperature of the room is 60°F, and if the emissivity is 0.811, then Calculate, the amount of radiant energy delivered to the room by the stove each second (KW)

(iv) Convert 129 J/kg°C to cal/g°c (a) 5.3x105 (b) 0.031 (c) 32.44 (d) 30.8

(a) If the heat capacity of an electric jug is 500 J °c1, how much heat energy does it absorb when heating 1.5 L of water, specific heat 4200 J kg1 0c1, from 20°C to 95°C?

(I) Among the highest and lowest natural air temperatures claimed are 136°F in the Libyan desert and –129°F in Antarctica. What are these temperatures on the Celsius scale?

(II) When a 290-g piece of iron at 180°C is placed in a 95-g aluminum calorimeter cup containing 250 g of glycerin at 10°C, the final temperature is observed to be 38°C. Estimate the specific heat of glycerin

(I) To what temperature will 8200 J of heat raise 3.0 kg ofwater that is initially at 10.0°C?

(II) A 0.095-kg aluminium sphere is dropped from the roofof a 55-m-high building. If 65% of the thermal energy produced when it hits the ground is absorbed by the sphere, what is its temperature increase?
