Answer:
Only option A is correct. Beaker A has lower kinetic energy than beaker B.
Explanation:
Step 1: Data given
Beaker 1 has a volume of 100 mL at 25 °C
Beaker B has a volume of 100 mL at 60 °C
Thermal energy = m*c*T
Thermal energy beaker A = 100 grams*4.184 * 25°C
Thermal energy beaker B = 100 grams *4.184*60°C
⇒ Since both beakers contain the same amount of water, the thermal energy depends on the temperature.
Since beaker B has a higher temperature, it has a higher thermal energy than beaker A
When we heat a substance, its temperature rises and causes an increase in the kinetic energy of its constituent molecules. Temperature is, in fact, a measure of the kinetic energy of molecules.
This means beaker B has a higher kinetic energy than beaker A
Potential energy doesn't depend on temperature. this means the potential energy of beaker A and beaker B is the same.
a. Beaker A has lower kinetic energy than beaker B. This is correct.
b. Beaker A has higher thermal energy than beaker B. This is false.
c. Beaker A has higher potential energy than beaker B. This is false.
d. Beaker A has lower potential energy than beaker B. This is false
e. Beaker A has higher kinetic energy than beaker B. This is false.
