What are the factors that determine the amount of energy needed to raise the temperature?
Mass, heat capacity, the desired raise in temperature.
How much energy is needed to raise the temperature of 2.0 g of water 5.0 degrees C?
The needed energy is 10 calories.
A calorie is the amount of energy needed to?
raise the temperature of the body by 1 Celsius
What is needed for a change in state phase to happen?
Change in temperature or pressure/volume.
Does amount of light needed increase or decrease as one moves to higher magnification with the microscope?
The amount of light needed increases as one moves to higher magnification with the microscope. This is usually done by opening the light diaphragm.
Which is a mechanism of heat transfer?
A broad question, so I will give a broad answer. A driving force is needed and what drives heat transfer is simply temperature differences between two bodies. The mechanism at say a molecular level is really just the exchange of the energy from molecules to molecules. Higher energy molecules will collide with lower energy molecules and voila, you have heat transfer.
What conditions are needed for liquid water?
Temperature higher than freezing and lower than boiling.
Why high pressure needed in autoclave?
To sterilise effectively the water in the autoclave needs to reach a temperature of 120°C. Since water at atmospheric pressure boils at 100°C, a higher pressure is needed to reach that temperature.
Does water inside a vacuum boil at a higher or lower temperature than it does under normal pressures?
It boils at a lower temperature because of the less energy needed.
Which has higer rate of reaction the one with higher temperature or not?
The greater the temperature, the faster the rate of reaction. This is due to the fact that increasing temperature increases the activation energy, which is the amount of energy needed to get a reaction started.
What are needed to transfer a gene through a DNA molecule?
Genetics engineering is needed to transfer genes through DNA molecules.
What oil is needed for the transfer case of your 2001 Durango?
The transfer case uses ATF.
Where would one use an automatic transfer switch?
An automatic transfer switch would be used when one needs to switch energy from one source to another and cannot do it manually. It can be used to switch from electric to a generator when needed.
Is one hundred degrees Celsius is the boiling point water?
Yes, at normal atmospheric pressure - a higher temperature is needed at higher elevations. This is offset by some cooks at high elevations by use of a pressure cooker.
Does ice melt and boil at specific tempurtures?
Yes, usually water will melt at anything above 0 degrees celsius or boil at 100 degrees. However pressure and altitude can change the required temperature needed for boiling/melting. The higher pressure the lower temperature required and vice versa The higher altitude the less temperature needed
What is the Average temperature needed to grow wheat?
The average temperature needed to grow wheat is 17*c.
Why does an egg get hard boiled faster in salted water?
Because when you add salt to water you increase the boiling point (the temperature at which a fluid boils) and so you are cooking the egg at a higher temperature, therefore less time is needed.
