Answer:
The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.
Explanation:
Answer:
176984.38J
Explanation:
E = mC∆T
Where E is the energy in joules
M is the mass of water
C is the specific heat capacity of water =4.184J/g°C
It is known that it will take 4.184J of energy to change the temperature of water by one degree Celsius.
∆T = 98.6°c - 5.4°c
= 93.2°c
∆H = 454.3g × 4.18J/g°C × 93.2°c
= 176984.3768
176984.38J
all of the absorbed energy is converted to kinetic energy
Explanation:
When a gas is heated, all of the absorbed energy is converted to kinetic energy. This is because, according to the kinetic theory of gases, the average kinetic energy of gases is directly proportional to temperature.
- As the gas absorbs more heat, the potential energy it carries converted to kinetic energy.
- Potential energy is the energy at rest of a body
- Kinetic energy is the energy due to the motion of the particles of a medium.
- As more heat is added to a body, the kinetic energy continues to increase significantly.
- Eventually, all the absorbed energy is converted to kinetic energy as the gas expands more.
