There is a proportional relationship between the volume of a sample of helium in liters and the mass is of that sample in grams. if the mass of a sample in 5 grams, it's volume is 28liters. (5,28) is shown on the graph below

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

your answer is

a.
