7. a 5.0 g piece of metal is heated to 100°c, then placed in a beaker containing 20.0 g of water at 10°c.
the temperature of the water rises to 15°c. assuming that heat lost by the metal = heat gained by the
water. calculate the specific heat of the metal.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

there is none because earth is stationary and flat.
