What else can I help you with?
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.
What is 5 the percent of 20?
Five Percent of 20 would be 1.
How would you express 78 percent percent as a fraction?
78/100
How much is 2 percent of 1000?
2 percent of 1000 would be 20.
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 would a machine that had 100 percent mechanical efficiency be called?
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
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.
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
How could you measure the calorie content of a peanut in a laboratory?
You would burn it in a calorimeter :-)
What is water equivalent of calorimeter?
The water equivalent of a calorimeter is the mass of water that would absorb or release the same amount of heat as the calorimeter itself for a given temperature change. It is a way to express the heat capacity of the calorimeter in terms of water, facilitating easier calculations in calorimetry experiments. The water equivalent is calculated by considering the specific heat capacity of the calorimeter's materials and their mass. This concept helps in determining the overall heat transfer during thermal processes.
What is the percent efficiency of a 60W light bulb that produces 6W of light energy?
The percent efficiency would be calculated by dividing the useful output by the total input energy and multiplying by 100. In this case, the useful output is 6W (light energy produced) and the total input is 60W (electricity consumed). Therefore, the efficiency would be (6/60) * 100 = 10%.
Can a machine have 110 percent efficiency?
Nothing can be more that 100% (one hundred percent)! When people say that something is one hundred and ten percent - they are wrong. It is an attempt to imply that something is greater that it should be. It is similar to the annoying habit of adding !!!! at the end of a sentence, when a single ! is correct.
What temperature would the cold reservoir need to be for a Carnot engine to achieve 100 percent efficiency?
For a Carnot engine to achieve 100 percent efficiency, the temperature of the cold reservoir would need to be absolute zero (0 Kelvin). This is because the efficiency of a Carnot engine is given by 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir, and efficiency is maximized as Tc approaches absolute zero.
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.
Would a calculation of the atomic mass of a metal be too high or too low if your hot metal sample cooled off while being transferred to the calorimeter?
If the metal sample cooled off during transfer to the calorimeter, the atomic mass calculation would likely be too low. The cooling of the sample might cause a loss of energy, leading to a lower measured heat capacity and an underestimation of the atomic mass.
