I need an hypothisis on How does temperature change affect surface tension?

Biology
1 answer:
Dafna1 [17]3 years ago
4 0

Hypothesis: I believe an increase in temperature would lead to a decrease in surface tension.

Here's why: As the temperature increases, the molecular interaction between the liquids molecules becomes weaker because the hydrogen bond is the main factor for association between two molecules. It is a very weak bond to begin with, so when the temperature increases, it just further weakens it.

Which convection cell in the atmosphere lies to the north of the polar jet stream
zepelin [54]

The correct answer is polar cell.

Polar cell is termed as the transport of heat to polar latitudes from tropical to be accomplished.

Examples of cells which are found in the hemisphere include ferrel cells, polar cells, and Hadley cells.

Convection cell is termed as a phenomenon which is known to occur when there is a difference of density in the body of gas or liquid.

The difference occurs when there is rising and falling of currents. Any fluid from conventional cell can be formed. For example in the earth atmosphere.

Match the description on the right with the force on the left.
Marat540 [252]

Magnetic force - B.

Electrical force - A.

Gravitational force - D.

Contact force - C.

<h3><u>Explanation:</u></h3>

When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.

Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.

The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.

A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.

Oxana [17]
The plant cells contains- cell wall, central vacuole
the animal cell have- cilia cetrosomes
Both plant cells and animal cells contains - cytoplasm and mitochondrion 
The main structural differences between plant and animal cells are the additional structures found in pants. The structures include, the cell wall, the chloroplasts and also the vacuoles. The similarity between them is that they both contain plasma membrane, a nucleus, a nucleolus, mitochondria, ribosomes, endoplasmic reticulum, golgi apparatus, peroxisomes and the microtubules.
