Explanation :
Given equation
This equation is balanced. because the number of reactants is equal to the number of products.
According to conservation of matter and energy,
The conservation of matter and energy states that matter can not create and can not destroy but conserved. we can only change one form to another form of the matter and energy.
So, we can say energy conserved and the ,mass of the system always same over time.
Answer: The weight of an object is a force expressed in Newton (N). ... Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.
Explanation: Hope this helps :)
Answer:
The temperature raise is = 0.14 [C]
Explanation:
In order to find the temperature difference we must use the following equation:
But first we need to find the original volume V:
When the volume is increased the diameter will be larger:
D1 = 0.125[m] + 0.0002[m] = 0.1252[m]
Therefore the new radius will be:
r1=0.0626[m]
The new volume is:
Replacing all the calculated values in the equation:
Answer:
when current is passed through a hot plate, it converts <u>electric</u><u> </u>energy into <u>heat</u><u> </u>energy
