Answer:
187 J
Explanation:
First Law of Thermodynamics :
ΔQ = ΔW + ΔU
ΔQ : Heat. If it added to system then positive and if it is rejected by system then negative.
ΔW : Work. If it done by the system then positive and if it is done on system then negative.
ΔU : Internal Energy. If it positive then temperature of system increased and if it is negative then temperature of system decreased.
ΔQ = 79 J
ΔW = - 108 J
ΔU = ?
substituting the value in the equation:
79 = -108 + ΔU
∴ ΔU = 187 J
Answer:
The weight of an object at the Earth's South Pole is slightly more than its weight at the Equator because the polar radius of the Earth is slightly less than the equatorial radius. Though the mass of an object remains constant, its weight varies according to its location.

The levels of critical thinking classify people into six categories depending on their ability to reflect.
<h3>What is critical
thinking?</h3>
This refers to the ability to analyze information, situations, etc. as well as apply, synthesize or evaluate the information learned.
<h3>What are the levels?</h3>
According to Dr. Ridel, the levels are:
- Unreflective thinking: They do not reflect on information and lack the skills to have critical thinking.
- Challenged thinker: This person knows critical thinking is important but has difficulties to have critical thinking.
- Practicing thinker: This person has better-thinking abilities.
- Advanced thinker: This person can critically think and has the skills to improve this process.
- Master thinker: This person is in control of this process and shows superior thinking abilities.
