One kilocalorie is the amount of energy required to heat one kilogram of

water by 1 degree Celsius. The regular human needs about 2,000kilocalories

(Calories) to survive each day in a healthy manner. If we were able to transfer

ten percent of our energy to heat water (instead of using it to live) how hot would

a kilogram of water be at the end of the day?

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
