flammable
Explanation:
flammble is about flame in it so chemical
B) A chemical property

Answer: An amount of 
heat is required to raise the temperature of 4.64kg of lead from 150°C to 219°C.
Explanation:
Given: mass of lead = 4.64 kg
Convert kg into grams as follows.
The standard value of specific heat of lead is 
.
Formula used to calculate heat is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat of substance
= change in temperature
Substitute the value into above formula as follows.
Thus, we can conclude that heat is required to raise the temperature of 4.64kg of lead from 150°C to 219°C.
Answer:
Radio waves
Explanation:
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
