What would be your best course of action if exposed to this hazard?

A. Make your TA aware of the exposure.
B. Wipe the affected area down with ethanol every day for 3 days.
C. Rinse the affected area with cool water for 10-15 minutes.
D. Run around the room screaming about your burn.
E. Visit the student health center if the area continues to burn, become discolored or irritated.

Option C) Rinse the affected area with cool water for 10-15 minutes.

Explanation:

Once exposed to burns, whether chemical or heat, rinse the affected area of the body with cool water, as water is known to dissolve all burning particles attached to the skin, and cool off the blood vessels lying beneath the burned surface.

Unlike other options provided, rinsing affected area with cool water is the best first aid for skin burns

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
