What is one one-hundredth of a percent?
That would be shown as .01%. So you would multiply the number by .0001 to get one hundredth of a percent. One Hundredth of a percent of 1239 would be .1239, one tenth would be 1.239, one percent would be 12.39 and ten percent would be 123.9.
What is 5 percent of 1500 dollars?
Well...if you drop a 0 for ten percent that would be 150. So half of that would be 5 percent which is 75.
How would you express 78 percent percent as a fraction?
78/100
What is 5 the percent of 20?
Five Percent of 20 would be 1.
How much is 2 percent of 1000?
2 percent of 1000 would be 20.
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
If efficiency of converting chemical to thermal energy was 90 percent what would the overall efficiency be?
In saying what the overall efficiency would be, I suppose you mean for other processes, creating the chemical energy for example, and using the thermal energy. This is impossible to answer, not knowing what these processes are.
What kind of cup would you use to make a calorimeter?
Styrofoam Cup
What kind of cups would you use to make calorimeter?
Styrofoam Cup
What would cause a percent yield to be over 100 percent?
Impurities in the substance can cause a greater percent yield. I recommend redoing the lab for better results.
If the output of the secondary of a transformer is 1300 watts and the input of the primary is 1800 watts the percentage efficiency would be?
72 percent
Why would a machine with 100 percent efficiency be considered an ideal machine?
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
How could you measure the calorie content of a peanut in a laboratory?
You would burn it in a calorimeter :-)
Why isn't it possible to attain an efficiency of 100 percent in heat engines?
Because unavoidably there would be a loss of energy during the process
An ideal machine would have an efficiency of?
A ideal machine would have an efficiency of 100 percent. For this to be possible, the amount of energy output by the machine would equal the amount of energy input. Because all machines have physical parts, some energy is lost to friction, heat dissipation, or other factors, so no machine can be an ideal machine.
What is the importance of wiping the ice dry before introducing it to the water in the calorimeter and how would it affect the outcome of the experiment?
The specific heat of water is different from the specific heat of ice and so 'wet ice' into a calorimeter experiment can increase the mass of water in the calorimeter and become a source of unaccuracy.
What is the efficiency of an engine that gives off 70 percent thermal enery?
If this, ie 70%, is the total energy loss, it follows that the engine is producing 30% useful energy, so that is its thermodynamic efficiency.
