What are super giants?Supergiants are among the very big and very luminous stars. Supergiant stars are present at the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars have range between 3,400 K to over 20,000 K.
Some examples of super giants are-
The brightest star in the constellation Orion have blue-white supergiant, it is Rigel. Deneb is the brightest star in Cygnus. It is also a white supergiant. Delta Cephei is the famous star Cepheid variable is also a yellow supergiant and Betelgeuse, Antares and UY Scuti are red supergiants.

explain one or two things that adversely (negatively) affect the Earth's environment. How do you know that these things you're discussing are bad for the world around us?
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Answer:
Hello! The main thing I will be talking about today is two things that negatively affect the Earth's environment. Humans have impacted the physical environment is many ways, two being, overpopulation. Overpopulation is becoming a problem in this world. Accidental births are the main reason. Overpopulation can cause economic problems, over-farming, deforestation, and even water polluting. Second thing is, burning toxic fumes, and creating pollution. Pollution is a very, very bad thing. It can cause the atmosphere to fill up with fumes which aren't good for plants, humans, or animals. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. There are four main types of air pollution sources: mobile sources, such as cars, buses, planes, trucks, and trains. stationary sources, such as power plants, oil refineries, industrial facilities, and factories. area sources, such as agricultural areas, cities, and wood burning fireplaces. I know the things I'm discussing are bad because, slowly the Earth is taking impact because of us. We need to make a better change and help our Earth.

Answer:
Melting and evaporation both represent changes in matter that involve behavior at the molecular level. We can see melting when ice becomes warm and changes to liquid, and we see evaporation when a puddle on the ground eventually disappears.

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap.
What process formed the water droplets in Scott’s model?
evaporation
transpiration
condensation
precipitation
The phase change process of condensation formed the water droplets in Scott’s model.
What is condensation?Condensation is a process of phase change in which gas molecules are converted to liquid molecules.
Condensation occurs due to the loss in heat and hence kinetic energy by the gas molecules.
In the water cycle model, after evaporation occurred in the water molecules, the process of condensation
formed the water droplets.
Therefore, condensation resulted in the formation of water droplets on the model.

Felix examined several photos of stars. To compare their temperatures, he looked at the colors of the stars. He organized the photos in order from coolest to hottest. Which of these answers shows the correct order?
Question 4 options:
Red, yellow, white, blue
Yellow, white, blue, red
White, blue, yellow, red
Blue, yellow, white, red
The correct order that lies between the color and temperature should be considered as the Red, yellow, white, blue.
The Correct order of stars:We know that the hotter body has the high temperature and the coldest body should be at the lower temperature.
Also, We can say that when the star is hotter that means it has the high temperature so there should be more blue which denotes the cool color and when the star is cooler the more is red which means low temperature. Also, red is a hot color.
Hence, the first option is correct.
