A scientist wants to determine which fertilizer is more effective—Fertilizer X or Fertilizer Y. The best way for her to proceed
Alecsey [184]

Answer:

The correct answer is "three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer".

Explanation:

I had to look for the problem to know the options.

The best way to determine which fertilizer is most effective is to have three evaluation groups. One group will be tested with fertilizer X and another with fertilizer Y. By leaving the third group without applying fertilizer, this will be the general pattern for comparing the effectiveness of the other two.

Have a nice day!

What type of heat transfer is a beaker on a hot plate an example of?
sesenic [268]

Heat transfer to a beaker on a hot plate is an example of conduction.

Explanation:

Conduction is a process where heat is transferred from one particle to another particle. Conduction is mainly possible in case of solids.In case of solids the atoms as well as the molecules are tightly packed through which the kinetic energy can easily pass. Conduction takes place when both the objects are touching each other. But in case of liquids molecules are loosely packed as a result convection takes place.

A gas has a volume of 543 ml. at a temperature of 75.0°C. What volume will the gas occupy at 20.2°C?
alexandr1967 [171]

Answer:

V₂ = 457.49 mL

Explanation:

Given that,

Initial volume, V_1=543\ mL

Initial temperature, T_1=75^{\circ} C=75+273=348\ K

Final temperature, T_2=20.2^{\circ} C=20.2+273=293.2\ K

We need to find the final volume of the gas. The relation between the volume and the temperature of the gas is given by :

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Put the respected values,

V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{543\times 293.2}{348}\\\\V_2=457.49\ mL

So, the final volume of the gas is equal to 457.49 mL.
