Ethanol is: flammable, liquid at room temperature, the boiling point is 78.37 ° C.
Answer :
- Nuclear fission : In nuclear reaction, the nucleus of a larger atom breaks into two or more smaller nuclei. In fission process, protons and neutrons are produced and larger amount of energy is released.
Example : In nuclear power plant, the energy released from the process of nuclear fission which is converted into electrical energy that is used in our homes and factories.
- Nuclear fusion : In nuclear reaction, the nuclei of two or more smaller atoms combine together to form single larger molecule. In fusion process, the mass of the resulting nuclei is more as compared to the starting nuclei and large amount of energy is also released.
Example : This process occurs in the sun and stars. In this, the isotopes of Hydrogen, Tritium and Deuterium combine together to form a neutron and a helium atom under high pressure and temperature.
Answer:
The pressure will increase due ot expnasion of gasses in a closed sealed tube tube .
Explanation:
That would be 0.5 g/ml because Density is equal to mass divided by volume and 8.5 is half of 17.
Answer:
Wind
Explanation:
Wind is renewable because we have an unlimited amount unlike coal, oil, and natural gas.
