Answer:
Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
Explanation:
The nine activities that scientists engage in as a part of scientific inquiry are the following:
1. Observe
2. Define the problem
3. Form a study question
4. Research the problem
5. State the expectations (hypothesis)
6. Experiment and gather data
7. Analyze the results
8. Reflect on the findings
9. Communicate with the wider community
Answer:
physical change should be the answer
<span>You needed a quick boost of energy - MONOSACCHARIDE
You wanted to grow strong nails, you haven't eaten in days - PROTEIN
You wanted to grow healthy hair - PROTEIN
You had a race tomorrow afternoon - POLYSACCHARIDE
You were getting ready for hibernation - LIPIDS
You wanted to get bigger muscles - PROTEIN
Your meal will be in a week - LIPIDS
CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants.
PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.
LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>
Therefore, in Doppler Effect only the frequency and wavelength are changes and the wave speed does not change
