Hello there!
In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:
We are to calculate the specific heat of the ethanol as shown below:
Thus, by plugging it the given data we can obtain:
Regards!
Hydrogen, helium and oxygen
Answer:
2 and 3 because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4. The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus. The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.
