Answer:
1: energy
2: converts
Kinetic energy is either 3 or 4, those questions are really similar.
Answer:
b.open flame because it is fundamental end of the alcohol mixes in with the flame then it will become a bigger fire
The atoms of the reactant rearrange to form new products.
Well, first of all, the formula for finding potential energy is;
PE=mgh
Where; m is the mass
g is the gravitational force or acceleration due to gravity
h is the height.
Anyway, according to the question, the mass is 1kg, the acceleration due to gravity has a constant value of 10ms² . And the height is 3m. Now you just have to use all these in the formula. So;
mgh= 1 x 10 x 3. That will be 30. And the unit of potential energy is Joule. So the answer is 30 joules. Hope i helped. Have a nice day.
Answer:
D
Explanation: Decreasing the temperature of the system would lower the reaction rate.
