1. Two students were discussing the color of a blue paper. Student A said, The paper looks blue because the paper reflects light of a specific wavelength that our eye sees as blue.

Student B said, The paper looks blue because the paper reflects light of a specific frequency that our eye sees as blue.

What would you say to these students to help them understand?

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

clouds form

solid ice forms on leaves.

water droplets form on grass.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
