Because on burning plastic produce toxic gases which is harmful for our earth
Answer is: thermal conductuction.
Thermal conductuction is the transfer of heat<span> through physical contact. </span>Thermal conduction<span> is the transfer of heat</span> by microscopic collisions of particles. <span>Heat spontaneously flows from a hotter to a colder body.
</span>The process of heat conduction depends on four basic factors: the temperature gradient<span>, the cross section of the </span>materials<span> involved, their path length and the properties of those materials.</span>
Answer:
Iron is like iron man.
Iron ore is what is on caves
Answer:
38.2836 kJ
Explanation:
Mass = 91.5g
Initial Temperature = melting point = 0 C = 273 K (upon converting to kelvin)
Final Temperature = Boiling point = 100 C = 373 K
Heat = ?
They are related by the equation;
H = mCΔT
ΔT = Final - Initial Temperature = 373 - 273 = 100 K
C = specific heat capacity = 4.184 J /gK
H = 91.5 * 4.184 * 100
H = 38283.6 J
To convert to kilojoules, divide by 1000. This leaves us with;
H = 38283.6 / 1000 = 38.2836 kJ
The answer is (2). The electrolytic cell mechanism is to convert the electrical energy to chemical energy. So it need external energy source. And there is a similar one called voltaic cell which will convert the chemical energy to electrical energy.
