The correct answer is false. A compound microscope can magnify something up to 200 times and further. A compound microscope is a microscope with more than one lens and its own source of light. Today's strongest compound microscopes have magnifying powers of 1000 times to 2000 times.

The correct answer is False

Explanation:

A microscope is an instrument used in many scientific fields including biology and chemistry to magnify the image of an object and therefore study and look at it, which is not possible without a microscope due to the limitations of the human eye. Additionally, a compound microscope is a type of microscope that includes multiple lenses to magnify objects and therefore, allows scientist to observe the same object with different sizes. About this, it is important to mention the range objects can be magnified depends on the type of microscopes but in general terms, this type of microscope include lenses that magnify objects from 10 times to around 400 times, and especial microscopes can magnify objects up to 1000 times. Thus, it is false a compound microscope can magnify something only up to 200 times.

What is the resultant pressure if 1.7 mol of ideal gas at 273 K and 2.79 atm in a closed container of constant volume is heated
dedylja [7]

Answer: The resultant pressure is 3.22 atm

Explanation:

Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T     (At constant volume and number of moles)

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1 = initial pressure of gas  = 2.79 atm

P_2 = final pressure of gas  = ?

T_1 = initial temperature of gas  = 273K

T_2 = final temperature of gas = 315 K

\frac{2.79}{273}=\frac{P_2}{315}

P_2=3.22atm

Thus the resultant pressure is 3.22 atm

Do x-rays travel slower than infrared
OleMash [197]
No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.
