- 1-67 If 168 g of an unknown liquid requires 2750 cal of heat to raise its temperature from 26oC to 74oC, what is the specific heat of the liquid?arrow_forward1-91 In calculating the specific heat of a substance, the following data are used: mass = 92.15 g; heat = 3.200 kcal; rise in temperature = 45oC. How many significant figures should you report in calculating the specific heat?arrow_forward1-93 The specific heat of urea is 1.339 J/g . If one adds 60.0 J of heat to 10.0 g of urea at 20oC, what would be the final temperature?arrow_forward
- 1-68 The specific heat of steam is 0.48 cal/g oC. How many kilocalories are needed to raise the temperature of 10.5 kg of steam from 120oC to 150oC?arrow_forward1-87 Water that contains deuterium rather than ordinary hydrogen (see Section 2-4D) is called heavy water. The specific heat of heavy water at 25oC is 4.2 17 J/g oC. Which requires more energy to raise the temperature of 10.0 g by 10oC, water or heavy water?arrow_forward1-78 The kinetic energy possessed by an object with a mass of 1 g moving with a velocity of 1 cm/s is called 1 erg. What is the kinetic energy, in ergs, of an athlete with a mass of 127 lb running at a velocity of 14.7 mi/h?arrow_forward
- Which is the higher temperature, 15C or 4F?arrow_forward1-76 If the density of air is 1.25 10-3 g/cc, what is the mass in kilograms of the air in a room that is 5.3 m long, 4.2 m wide, and 2.0 m high?arrow_forwardEnergy conservationists suggest that air conditioners should be set so that they do not turn on until the temperature tops 78 F. What is the Celsius equivalent of this temperature?arrow_forward
