strongest and weakest acid among the following​

Answer:

A refrigerator is a popular domestic machine that has a thermally insulated compartment and a heat pump that transfers heat from inside the refrigerator to the external environment so that the temperature inside the refrigerator is lower than the ambient temperature of the room.

Nowadays refrigerator is used to preserve food in almost all countries, it reduces the reproduction rate of bacteria because they cannot breed in low temperature.

Keeps the refrigerator temperature slightly above the freezing point, the temperature is kept at 3-5 degrees (37 to 41 degrees F) to keep food safe.

Any machine whose temperature is below freezing point is called Freezer.

Answer:

A refrigerator is a popular domestic machine that has a thermally insulated compartment and a heat pump that transfers heat from inside the refrigerator to the external environment so that the temperature inside the refrigerator is lower than the ambient temperature of the room.

Nowadays refrigerator is used to preserve food in almost all countries, it reduces the reproduction rate of bacteria because they cannot breed in low temperature.

Keeps the refrigerator temperature slightly above the freezing point, the temperature is kept at 3-5 degrees (37 to 41 degrees F) to keep food safe.

Any machine whose temperature is below freezing point is called Freezer.

Even before the fridge, a machine was used to keep cool, which was called icebox, but the refrigerator replaced it.

The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacte- ria (which all food contains) so that it takes longer for the bacteria to spoil the food.

ADVANTAGES OF REFRIGERATOR:

We can store food in the fridge for a long time and keep it free from germs.

Some food items are get deteriorate quickly due to the outside environment, we can also keep them in the fridge and use them after a few days.

Even if the food is not wicked outside, there is a risk of insects getting bogged down, but the food is also saved from insects inside the fridge.

We keep drinking water, cold drinks, there is no use of drinking without cooling and in that sense, it is also very beneficial for us.

DISADVANTAGES OF REFRIGERATOR:

We have to keep the fridge continuously with 24 * 7 electricity and it costs a lot of electricity.

Although we use the fridge every day but pay very little attention to it, most of all we remember it in the summer season because we need cold water and a cold drink.

Answer:

80

Step-by-step explanation:

Given -

1000

we have to find out the 8% of 1000.

Percentage means divide by 100.

So we can write it as,

[tex] = \frac{8}{100} \times 1000[/tex]

By dividing 1000 by 100 we get,

[tex] = 8 \times 10[/tex]

[tex] = 80[/tex]

Hence,

The 8% of 1000 is 80.
