1. The bottle left in the sun is exposed to the thermal energy which causes it to heat up. Ice is cold and the bottle is in direct contact with the ice.

2. Its harder for cold winds to get through to you when theres 3 or even 4 layers of clothing on your body than one thick one.

3. Common Sense?... the rug is thick and the tile is... a tile

1. First, heat can be absorbed. This is along the lines of thermodynamics, where any material has a heat capacity. This increases the molecules velocity, thus creating a higher temperature than the soda in an ice bucket. In colder environments, the molecules velocities are much slower, creating less thermal energy because there is barely any movement involved. Friction is required for thermal energy to take place.

2. The reason as to why wearing two or three layers of clothing can help you keep warmer rather than just one is because as the air travels through your clothing, each layer provides a thermal insulation that can help keep you warm. Whereas a thick layer can only divide up that amount of work compared to the two or three layers that can either specialize in what the layer does or at least cuts the work out.

3. The rugs on the floor create an insulation where it prevents the loss of heat that it has already gained. Whereas the tiles, don't have that type of heat retention due to the material it is made from. All materials are able to insulate heat somehow. However, some materials are better than others, like wool or cotton.

When the plant cell is swallowed by water without exploding it is in what case
tamaranim1 [39]

Answer:

It is in hypotonic case.

Explanation:

The plant cell is in hypotonic case because the the solute concentration outside the cell is lower than in the cell. Plant cell do not burst in hypotonic solution because they have a cellulose cell wall outside its cell membrane. The cell wall is permeable and it's prevent the cell from bursting after it absorb water through osmosis.

What’s the difference between an objects mass and weight. How do I calculate the weight of an object? Which one is affected by g
vagabundo [1.1K]

Answer:

The mass of an object is a measure of the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. Mass does not change with gravity as weight does due to the act of pulling down on an object making it in fact heavier.

Which of the following can NOT be prevented with a vaccine?
grandymaker [24]

Answer:

listeriosis

Explanation:

  • A vaccine is used to provide active acquired immunity to the host by supplying them with a biological preparation which is often made up of attenuated organism, its associated immunogenic particle, protein, DNA, etc. 
  • Today there are vaccines available for a wide variety of diseases however there is no preventive vaccine for listeriosis.
  • Listeriosis is a disease caused by <em>Listeria monocytogenes</em> and it is a very serious disease often caused due to the consumption of contaminated food. 
  • There is unavailability of a commercially available vaccine against listeriosis although a lot of research is underway to prepare a vaccine to reduce the mortality rate.
