5.00 g of carbon were adiabatically burned to co2 in a 2.00 kg copper calorimeter which contained 2.50 kg of water. the temperature increased by 14.1 °c.
specific heats: copper, 0.385 j k⁻¹ g⁻¹; water, 4.184 j k⁻¹ g⁻¹.

a) determine the heat of combustion of carbon ignoring any heat absorbed by the calorimeter.
b) now determine the heat of combustion considering the heat absorbed by the calorimeter.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
