What is the formula for change in temperature?
Change in temperature = New temperature minus Old temperature.
How do you find out pi with the circumference and diameter?
pi is the circumference divided by the diameter. it is a set universal constant and will never change = 3.1415...
How many joules of energy are required to raise the temperature of 20g of aluminum from 10 degrees C to 15 degrees C?
Heat energy Q = mass x specific heat capacity x temperature change. Q = m*c*delta T Q = Joules m = kg c (aluminum) = 895.8 J/kg delta T = degr.C temp. change Answer: Q = (20/1000) x 895.8 x 5 = 89.58 Joules (Specific heat capacity of aluminum is obtained by multiplying its specific heat of 0.214 with c of water which is 4186 J/kg = 0.214 x 4186 = 895.8 J/kg).
Does the relationship between the circumference and the diameter change when you use a different unit?
No. The units don't matter, the circumference always equals pi times the diameter. (This is only true of the circumference and diameter are in the same units. If for example, the circumference was in feet and the diameter in inches, the feet must be change to inches or the inches to feet in order for this relationship to be true.)
How does the change in the diameter affects the circumference?
It will make the circumference of the circle bigger or smaller
Could aluminum change to a gas state If so at what temperature?
possibly, it can into a liquid!
Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
Aluminum bends easily is physical or chemical change?
Aluminum bending is a physical change. This is because the aluminum is still the same aluminum as it was before just in a different shape.
What would be chemical change of aluminum?
If the aluminum bubbles it will be a chemical change.
Does the melting point of aluminum change with the thickness?
The melting point of any given substance (such as aluminum) has nothing to do with the thickness or shape of the material being melted. It will melt at the same temperature. But it does require more heat in order to heat a thicker piece of aluminum to its melting point.
When an object moves in a circular path will the velocity change will there be acceleration?
When an object moves in a circular path, the velocity will change and the there will be acceleration.
How do you change a diameter to a radius?
The radius is half the diameter.
How do you change diameter to radius?
Divide the diameter by 2.
How do you change circumferance into diameter?
circumference/pi = diameter
Is tearing aluminum foil a chemical change or physical change?
Physical. It's still aluminum foil.
Is aluminum foil cut in half a physical or chemical change?
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
