Answer:
The correct option is;
a. The particles will gain a large amount of kinetic energy
Explanation:
As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.
The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
Answer:
b. radicals form easily in the presence of chlorine radicals.
Explanation:
Chlorine radicals perform the first propagation step: because "radicals form easily in the presence of chlorine radicals."
This is because the first propagation step consumes a CHLORINE RADICAL while the second propagation step regenerates a CHLORINE RADICAL. In this way, a chain reaction occurs, whereby one CHLORINE RADICAL can ultimately cause thousands of molecules of methane to be converted into chloromethane with C12 present.
Hence, in this case, the correct answer is that "radicals form easily in the presence of chlorine radicals."
Answer:
No
Explanation:
A single property is not conclusive for identifying a substance. For example, conductivity. Copper, aluminum, and lead all conduct electricity, yet they have different atomic number, electronegativity, and physical properties, thus their shared property of conducting electricity is not enough to correctly identify each substance.
Answer : The amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.
Explanation:
Heat capacity : It is defined as the heat required to raise the temperature by one degree.
Specific heat capacity : It is defined as the amount of heat required by one gram of a substance to raise its temperature by one degree Celsius.
The heat required to change the temperature of a substance is related to heat capacity of the substance by the expression as :
where,
C = specific heat capacity
m = mass of a substance
q = heat required
= change in temperature of substance
Hence, the amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.
