Explanation:
Energy: Light, heat, kinetic and potential energy, and sound are non-matter because they are massless. Objects that have mass and are matter may emit energy.
1.True
2.False
3.B
4.A
5.True
Answer:
Hope this helps
Explanation:
Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.
Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.
Differences:
Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.
• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.
• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.
• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.
<u>Answer:</u> The concentration of HBr sample is 0.1025 M
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is HBr
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of HBr sample is 0.1025 M
