Density is mass divided by volume (d = m ÷ v). Based on the graph, what happens to a fixed mass of water when it is cooled from 4°C to 0°C?
A.
volume increases and density decreases
B.
volume decreases and density increases
C.
volume increases and density increases
D.
volume decreases and density decreases
Answers
Answer:
The answer is A, Volume increases and density decreases
Explanation:
When water is cooled from 4°C to 0°C, the volume of water increases and density decreases. Thus, the correct option is A.
What is the Density of water?The density of water may be defined as the weight of the water per unit volume, which depends on the temperature of the water. The normal density of water is 997 kg/m³.
When the temperature of liquid goes down, the density of its gradually decreases, as a result of this, the volume considerably increases.
Therefore, the correct option for this question is A.

Convection Currents
Mantle

Heat
Less dense
movement
More dense
Answers
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.HELP PLS Using the picture below, which wave would have a higher pitch.

Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
Answers
Answer:
Charakan
Explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.

Explanation:
Objectives of the microscope have magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. The nosepiece is found between the stage and the eyepiece or ocular lens. Glass slide is the slide where a specimen is placed for the study and covered with a coverslip, bubble should be avoided while placing the coverslip.
Mirrors need to adjust to seeing the field of view by adjusting the light. After computing the magnification there would be a final image of the specimen that would be inverted due to the two lens used here.
