How could the pressure of a gas increase if temperature is constant?
Yakvenalex [24]

Answer:

Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.

Stels [109]

Answer:

The correct answer is  b. He determined that DNA contains four nitrogenous bases.

Explanation:

Levene was an American biochemist who studied the structure of DNA in the early 1900s and in 1920 he found that DNA consists of four nitrogenous bases that are Adenine, Guanine, Thymine, Cytosine.

He also found deoxyribose sugar and phosphate group and said that nucleotide is the basic unit of DNA which contains a ribose sugar with attached nitrogenous base and phosphate group.

He also concludes that an equal amount of adenine, guanine, thymine, and cytosine makes the DNA which is now known as tetranucleotide hypothesis. So the correct answer is b. He determined that DNA contains four nitrogenous bases.

Equal masses of granite, iron, copper, and lead are placed in sunlight. Based on specific heat, which material will warm up the
levacccp [35]

Answer:

Lead

Explanation:

The material that will warm up the fastest would be<u> lead.</u>

<em>The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit of the substance by one degree. The higher the specific heat capacity of a substance, the higher the amount of heat required to raise the temperature of the substance and vice versa.</em>

The specific heat capacity (in J/g °C) of granite, iron, copper, and lead are as follows:

Granite - 0.790

Iron    - 0.450

Copper - 0.385

Lead - 0.129

From the table, <u>lead has the lowest specific heat capacity, hence, it will be the fastest to get warmed when equal masses of all the substances are placed in the sunlight.</u>
