Answer:

C. Water expands on cooling below 4 °C, increasing in volume until it reaches 0 °C.

Explanation:

The volume occupied by ice is greater than the volume of water.

The maximum density of water is at 4°C.

The hydrogen bond in ice gives it an open cage like structure which makes it volume higher and density lower as compared to liquid water. As we increase the temperature the volume decreases due to breaking of these bonds so its density increases till 4°C. After this temperature the increase in volume due to change in state is more and thus its volume increases and density decreases.

How humans can improve the negative aspects of soil use FULL SENTENCES 50 POINTS PLEASE HELP
katen-ka-za [31]

Answer:

Using diverse nutrient sources can help maintain soil health. Manure and compost add organic matter as well as an array of nutrients, but using just compost or manure to meet the nitrogen needs of the crop every year can result in excessive phosphorus levels in the soil.

Dalton's law of partial pressures states that the total pressure exerted by a mixture of gases is the sum of the pressures exert
Damm [24]

Answer: The given statement is true.

Explanation:

According to the Dalton's law, total pressure of a mixture of gases that do not react with each other is equal to the partial pressure exerted by each gas.

The relationship is as follows.

          p_{total} = \sum_{i=1}^{n} p_{i}

or,        p_{total} = p_{1} + p_{2} + p_{3} + p_{4} + ......... + p_{n}

where,  p_{1}, p_{2}, p_{3} ....... = partial pressure of individual gases present in the mixture

Also, relation between partial pressure and mole fraction is as follows.

                 p_{i} = p_{total} \times x_{i}

where,      x_{i} = mole fraction

Thus, we can conclude that the statement Dalton's law of partial pressures states that the total pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture, is true.
