Which two forms of heat transfer work together to heat water in a plastic bottle

Chemistry
1 answer:
Brums [2.3K]3 years ago
5 0
The primary form of heat transfer taking place within the water bottle will be convection, which is the natural circulation of fluid due to density differences arising from temperature differences. 

The second form is dependent on how the heating is taking place. If the bottle is out in sunlight, the form of heat transfer is radiation from the sun's rays. If heat is directly being applied to it, then the form is conduction, which occurs in solids and through direct contact.

You've made the hypothesis that the less rainfall a cactus plant gets, the taller it will grow, since cactuses like dry conditio
Leviafan [203]

A. the height of the cactus plants

Explanation:

The dependent variable in this experiment designed to test this hypothesis is the height of the cactus plants.

In a hypothesis statement, we can always deduce the dependent and independent variables.

  • Independent variables do not rely on other variables. They are usually the cause of the phenomenon observed in an experiment. In this experiment, it is the rainfall on the cactus plant.
  • Dependent variable is that variable that relies on the independent variable. It is usually the effect of changes in independent variable.
  • The height of the cactus plant depends on the amount of rainfall in an area.

Which has more calories: table sugar or aspartame?
Alina [70]
Aspartame produces 4 kilocalories of energy per gram when metabolized, While table sugar produces 3.9 kilocalories. However, aspartame is approximately 200 times sweeter than table of sugar, so it is consumed in much smaller doses. Then we can say that they're pretty much the same

When a substance is heated, what causes its properties to change?
hoa [83]

The molecules vibrate when the substance is heated, and the shape of the substance begins to form a different shape. For example: when you hear up metal it will melt becuase its molecules are changing and moving.

If 16.00 g of O₂ reacts with 80.00 g NO, what is the excess reactant? *<br><br> A.O₂<br> B.NO
Fed [463]

Answer:

  B. NO

Explanation:

In each mole of NO, the weight of the oxygen is 16.00 g; the weight of the nitrogen is 14.01 g. Then in 80 g of NO, we have 42.65 g of oxygen and 37.35 g of nitrogen.

__

In each mole of NO₂, the weight of the oxygen is 2(16.00) = 32 g. The weight of the nitrogen is 1(14.01) = 14.01 g.

From the available oxygen, we can produce ...

 (42.65 g +16 g)/(32.00 g/mol) = 1.83 mol of NO₂

From the available nitrogen, we can produce ...

 (37.35 g)/(14.01 g/mol) = 2.67 mol of NO₂

Clearly, the reaction is limited by the amount of available oxygen.

NO is the excess reactant.
