The surface tension of isopropyl alcohol in air has a value of 22.39 units and
the surface tension of water in air is 72.86 units. Which two statements are
true?
A. Isopropyl alcohol will have a higher boiling point than water
because the forces between the molecules are greater.
B. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller.
c. Isopropyl alcohol will have a more curved meniscus than water
because the forces between the molecules are greater.
D. Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller.
Answer:
B. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller.
D. Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller.
Explanation:
Isopropyl alcohol will have a lower boiling point than water because the forces between the molecules are smaller. Isopropyl alcohol will have a flatter meniscus than water because the forces between the molecules are smaller. Hence, options B and D are correct.
What is surface tension?Surface tension is the force that acts parallel along the surface of a liquid which in turn makes the surface of the liquid behaves like an elastic material.
Surface tension, as the name implies, acts on the surface of a liquid giving it some elastic properties; it is a product of the inherent properties of the molecules of the liquid.
For example, water possesses surface tension which is why when a pin or a needle is gently placed on the surface of the water it floats. Surface tension also accounts for the fact that some insects can walk on water.
Hence, options B and D are correct.

Amani wants to know if crushed ice or whole ice melts faster. She puts the whole ice in a bowl on the kitchen counter. She puts the crushed ice in a bowl in the oven. Lastly, she times both bowls of ice to see which melts fastest. Is this a valid experiment? Why or why not?
Yes,
Because she wants to know which melts faster so she puts a bowl of crushed ice in a oven, which in then can melt it. If she turns on the oven light she will be able to understand if it melts.
If she leaves it out on the counter the regular un-crushed ice, she can see if that is also melted faster but this is in fact a valid experiment.

Here at science made simple we are keen to inspire not only the next generation of scientists but also the next generation of science communicators. Supporting work experience students each year is an important part of what we do. Our work experience students get a chance to see a range of the activities that science made simple is involved with and we always set them challenge to produce some science communication themselves, whether designing a demo, delivering a short presentation or, in this case, writing a blogpost that includes all of these!
We hope you enjoy this from one of our latest work experience students, Bilaal, we loved having him in the office and think he’s got a promising career ahead of him.

Explanation:
the half-life of sodium-24 is 15 days. A laboratory technician measures out a 72 g sample. Approximately how many grams of sodium-24 would remain after 45 days?
Answer: 9 grams left After 45 days
Explanation:
Given,
Half life of sodium-24 = 15 days
Measured Sample = 72 grams
After 45 days how many grams remains is :
Number of half lives = time elapsed / half life
Number of half lives = 45 days / 15 days
Number of half lives = 3
At time zero total amount = 72 g
After first half life = 72 g/ 2= 36 g
At 2nd half life = 36 g/2 = 18 g
At 3rd half life = 18 g/2 = 9 g
Hence After 45 days 9 grams left.

How does the ocean affect the rate of accumulation of [tex]CO_{2}[/tex] in the atmosphere?
increases it
decreases it
maintains it at a constant rate
Answer:
The ocean is a large CO2 sink because of its large surface area. The CO2 emissions are caused by human and manufacturing activities which some of them are absorbed in the ocean because CO2 is partly soluble in water. Thus, the answer is CO2 is decreased in the process.
CO2 is part of the carbon cycle and as such, moves from the land to the atmosphereby human burning of fossil fuels and forest fires,. But CO2 also moves from the atmosphere into the oceans when when the solubility is right - this is called an ongoing "flux" or movement of CO2 in and out of the oceans. Hence the oceans act as a kind of buffer to ensure that not too much CO2 remains in the atmosphere and hence the greenhouse effect will not get too strong.When the oceans are colder, they can absorb more CO2 out of the atmosphere, and when they warm up, they tend to release it back into the atmosphere. However, global warming is also now transferring heat from the atmosphere to the oceans and so the oceans are less inclined to absorb excess CO2 from the atmosphere. Also, as the oceans absorb excess CO2 from the atmosphere, this tend to make the salinity of the oceans become more acidic.
