What mass of ice would it take to lower the temperature of 0.5kg of water from 20°C to 0°C. 7. A 100-g piece of iron is heated to 100°C and then dropped into a cavity in a large block of ice at 0°C. How much mass of ice will melt? 8. 50 grams of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C. The final temperature of the water in the...

1. Heat opens capillaries and improves blood flow. The reverse is true too: cold capillaries close. Thus, for a black eye where you want to prevent blood buildup causing painful swelling, you use ice. Now consider a patient who is told to keep hot compresses on an eye infection for 10 minutes. She discovers that her compress is no longer hot after only 5 minutes and therefore wants to keep it warm twice as long. Is the better strategy to use...

(33%) Problem 3: Warm blooded animals are home otherm that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun,...

Who Killed Kenny? At 2:45am on a night in 2006, Tammy, a maid who works in the house of multi-millionaire Kenny claims she was awoken by the sound of a loud thud outside her window. She got out of bed to discover that her employer had apparently fallen from one of his mansion's four balconies (1st, 2nd 3rd, and 4th floors). He was dead. Police arrived at 3:15am, and immediately noticed that Kenny was more than 7 feet horizontally away...

Since early Roman days, people have used greenhouses to grow plants—particularly to enjoy fruits and vegetables out of season. But not until the 1990s did greenhouses begin to gain popularity in the United States. The timing couldn’t be better. The amount of farmable land per capita in the world continues to shrink, and over the next 50 years, world population is expected to increase by 3 billion. At the same time, economists estimate the demand for farm products will double....
