Here's the equation you use: Density = mass/volume
1) 5.2g/cm^3 = m/3.7cm^3
2) m = 5.2g/cm^3 x 3.7cm^3
3) m = 19.24g
You can check the answer by plugging it in
19.24g/3.7cm^3
= 5.2g/cm^3
100 by 500 ml so if you put 50 ml in 630torr it would evaporate
Explanation:
it is more than ¹00 celcwius so it would eveporate
Answer:
A large quantity
Explanation:
A large quantity will take much longer to melt compared to a small quantity of the same matter.
The rate of melt of a substance is particularly a function of the nature of the substance and the amount of energy supplied to it.
If we assume that we are dealing with different quantities of the same substance, then the one that has more mass will melt faster because less energy would be required to change its state.
A large quantity of matter will take more time to melt.
Answer:
A = 0.023 m
Explanation:
The relation between the frequency of a radiation and its wavelength is given by the following expression.
where,
c is the speed of light (it has a constant value of 3.00 x 108 m/s)
A is the wavelength of the radiation v is the frequency of the radiation
In this case, the frequency is 13 GHz = 13 x
10° Hz = 13 x 1o° s-
The wavelength associated with this frequency is:
A = c/v = (3.00 x 10° m/s)/(13 x 10° s-") = 0.023
