A is the answer I know bc I take biology
Lord Kelvin, were he alive today, would be considered a Thermochemist. Thermochemistry is interested in the role of heat in chemical reactions. This includes the role of heat both as a biproduct of chemical reactions and a facilitator.
Kelvin's description of absolute zero is an important concept in thermochemistry. At absolute zero, there is no movement of molecules, and no energy available facilitate chemical reactions.
Answer:
The negatively charged rod will force a stream of water away from the rod because of the "attractive force. "
Explanation:
As we know that water molecules have been randomly arranged. So when a negatively charged rod is put near the stream of water, the molecules present in the water start rotating, unless the positive side will be close to the negative side of the rod. Which results in the generation of the attraction force. Hence, the stream of the water forces away the negatively charged rod. When the water molecules have polarized molecules in it the effect will be stronger than the dust.
The rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10²
<h3>What are significant figures?</h3>
Significant figures are figures that contribute to the general and overall value of the whole number.
Significant figures or digits are specifically meaningful with respect to the precision of a measurement.
Although, the original number given in this question has 9 significant figures, the number; 300.235800 can be rounded up to four significant figures as follows:
- Decimal notation: 300.2
- No. of significant figures: 4
- No. of decimals: 1
- Scientific notation: 3.002 × 10²
Therefore, the rounding up of the aforementioned number to four significant figures is as follows: 3.002 × 10².
