when John Travoltage rubbed his foot against the floor, he started building up negative energy, this negative energy later built up as he was rubbing his foot on the floor which then caused a reaction with the door knob, the same thing happened with the balloons, as we rubbed it on the sweater, the balloons started building up negative energy too, which then resulted in a connection with the positive energy. The dust particles most likely got a charge from moving around from different places, considering that fabrics build up the negative energy, it appears that the dust particles could have landed on a fabric which then allowed the particles to build it up and then stick to other surfaces.
A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Explanation:
The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
This phenomenon between the differences in land and water temperature causes land sea breeze to occur.
- Water has a very high specific heat capacity.
- This implies it takes more heat to cause a monumental increase in its temperature.
- It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.
A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.
Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.

Answer: B. Water breaks down into oxygen molecules for respiration.
Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.
This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
