17. A student places the ends of a curved copper bur into two insulated cups, as shown below. The copper
barist 20°C Cup 1 contains 40°C water and cup 2 contains 20°C water. Each cup contains the same
amount of water
Copper bar
Cup 1
Cup 2
20°C
A Describe the direction of heat flow between the cups of water in the first few minutes of the
Investigation and identify the primary method of heat transfer (conduction, convection, radiation)
between the cups of water. Make sure to describe how the transfer of heat occurred for the method you
identified
The direction of heat flow in the first few minutes is not to cold. The primary
method of heat transfer is conduction because the copper is in between the te
cups of water
75
B. After 25 minutes, the water in both cups reaches thermal equilibrium. Calculate the temperature at
which thermal equilibrium is reached.

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

One reason scientists are trying to develop fuel sources from corn and sugar is because these sources are renewable fossil fuels are being depleted these crops can be widely grown all of the above
