Temperature is a measure of "Molecular movement"
In short, Your Answer would be Option B
Hope this helps!
Answer:
t = 7.58 * 10¹⁹ seconds
Explanation:
First order rate constant is given as,
k = (2.303
/t) log [A₀]
/[Aₙ]
where [A₀] is the initial concentraion of the reactant; [Aₙ] is the concentration of the reactant at time, <em>t</em>
[A₀] = 615 calories;
[Aₙ] = 615 - 480 = 135 calories
k = 2.00 * 10⁻²⁰ sec⁻¹
substituting the values in the equation of the rate constant;
2.00 * 10⁻²⁰ sec⁻¹ = (2.303/t) log (615/135)
(2.00 * 10⁻²⁰ sec⁻¹) / log (615/135) = (2.303/t)
t = 2.303 / 3.037 * 10⁻²⁰
t = 7.58 * 10¹⁹ seconds
Answer:
uh i think its D All of the above
Explanation:
sorry if its wrong
Through the process of conduction, heat van be trnafered between two solids.
Answer:
Lightbulb: electrical energy to light energy
Alarm Clock: electrical energy to sound energy
Rollercoaster: electrical energy to mechanical energy
Riding a Bike: chemical energy to mechanical energy
Explanation:
Light bulbs, alarm clocks, and roller coasters require electrical energy to work. This energy then changes into the subsequent types. Light bulbs primarily emit that energy in the form of light, alarm clocks change that energy into sound, and roller coasters begin to move (mechanical). People power bikes, and the energy in our body is stored as chemical energy. So, when we rides bikes, that energy gets turned into moving (mechanical) energy.
