Make the following conversions. Show your calculations.

Natalija [7]

Answer:

1. 500 cm = 5 m

2. 1000 g = 1 kg

3. 455 L = 45, 500 cL

4. 0.865 m = 0.00865 m or 8.65 * 10^-3 n

5. 33.5 cm = 335 mm

6. 0.0198 m = 19800 micrometers

7. 57.65 cg = 5.765 * 10^8 nanograms

8. 1000 L = 1 kl

9. 99 degrees F = 37.222 degrees C

Explanation:

1. One meter = 100 centimeters

500 centimeters/ 100 centimeters = 5 meters

2. One kilogram = 1000 grams.

1000 grams/1000 grams = 1 kilogram

3. One Liter = 100 centiliters

455 liters * 100 centiliters = 45, 500 centiliters

4. One meter = 100 centimeters

0.865 centimeters/100 centimeters = 0.00865 meters

5. One centimeter = 10 millimeters

33.5 centimeters * 10 millimeters = 335 millimeters

6. One meter = 1.0 * 10^6 micrometers

0.0198 meters * 1 * 10^6 micrometers = 19800 micrometers.

7. One centigram = 1.0 * 10^7 nanograms

57.65 centigrams * 1 * 10^7 nanograms = 5.765 * 10^8 nanograms.

8. One kiloliter = 1000 L

1000 L/ 1000 L = 1 kiloliter

9. The formula for finding Celsius is 5/9(f - 32)

So 5/9(99 - 32) = x

5/9(67) = x

x = 335/9 or 37.222 degrees Celsius.

Define disphotic zone?

Llana [10]

Explanation:

The photic zone, euphotic zone, epipelagic zone, or sunlit zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column. The photic zone is home to the majority of aquatic life due to its location.

Photosynthesis in photic zone Edit

In the photic zone, the photosynthesis rate exceeds the respiration rate. This is due to the abundant solar energy which is used as an energy source for photosynthesis by primary producers such as phytoplankton. These phytoplankton grow extremely quickly because of sunlight's heavy influence, enabling it to be produced at a fast rate. In fact, ninety five percent of photosynthesis in the ocean occurs in the photic zone. Therefore, if we go deeper, beyond the photic zone, such as into the compensation point, there is little to no phytoplankton, because of insufficient sunlight.[1] The zone which extends from the base of the euphotic zone to about 200 meters is sometimes called the dysphotic zone.[2]

How many kilojoules of heat would be required to fully melt a 0.834 m³ block of ice , provided that the density of ice is 917 kg

Lerok [7]

2.54 × 10⁵ kJ of heat are required to fully melt a 0.834 m³ block of ice, with a density of 917 kg / m³.

<h3>What is melting?</h3>

Melting is a physical change in which solids turn into liquids.

Step 1. Calculate the mass of ice.

We have a block of 0.834 m³ of ice with a density of 917 kg/m³.

0.834 m³ × 917 kg/m³ = 765 kg = 7.65 × 10⁵ g

Step 2. Convert 7.65 × 10⁵ g to moles.

We will use the molar mass of water.

7.65 × 10⁵ g × (1 mol/18,02 g) = 4.24 × 10⁴ mol

Step 3. Calculate the heat required to melt 4.24 × 10⁴ moles of water.

According to the thermochemical equation, 6.01 kJ are required to melt 1 mol of water.

4.24 × 10⁴ mol × (6.01 kJ/mol) = 2.54 × 10⁵ kJ

2.54 × 10⁵ kJ of heat are required to fully melt a 0.834 m³ block of ice, with a density of 917 kg / m³.
