THERE ARE FIVE QUESTIONS YOU HAVE TO ANSWER
Question 1: Predict the answer to your question or the outcome of your investigation. Your hypothesis should take the form of an “If . . . , then . . . , because . . . ” statement.

Question 2:List all materials and write each step of your procedure. Identify any variables that are present as dependent variables, independent variables, and constants in your experimental group and your control group.

Question 3:How would you modify your procedure if you were to perform the separation again?

Question 4:How does knowing the properties of matter help you separate the substances in mixtures?

Question 5:Record all quantitative and qualitative data here

Which fators influence ocean currents

Orange juice has a lower or higher viscosity than chocolate syrup

Aheat engine running backward is called a refrigerator if its purpose is to extract heat from a cold reservoir. the same engine running backward is called a heat pump if its purpose is to exhaust warm air into the hot reservoir. heat pumps are widely used for home heating. you can think of a heat pump as a refrigerator that is cooling the already cold outdoors and, with its exhaust heat qh, warming the indoors. perhaps this seems a little silly, but consider the following. electricity can be directly used to heat a home by passing an electric current through a heating coil. this is a direct, 100% conversion of work to heat. that is, 19.0 \rm kw of electric power (generated by doing work at the rate 19.0 kj/s at the power plant) produces heat energy inside the home at a rate of 19.0 kj/s. suppose that the neighbor's home has a heat pump with a coefficient of performance of 4.00, a realistic value. note: with a refrigerator, "what you get" is heat removed. but with a heat pump, "what you get" is heat delivered. so the coefficient of performance of a heat pump is k=qh/win. an average price for electricity is about 40 mj per dollar. a furnace or heat pump will run typically 200 hours per month during the winter. what does one month's heating cost in the home with a 16.0 kw electric heater? what does one month's heating cost in the home of a neighbor who uses a heat pump to provide the same amount of heating?
