If 0.21J of heat cause a 0.308 degree C temperature change, what mass of water is present? a 0.0702 g
b 0.00540 g
c 0.163 g
d 18.4 g

The correct answer is Option c (0.163 g).

Explanation:

Given:

Heat energy,

Q = 0.21 J

Specific heat,

c = 4.184 J/g°c

Change in temperature,

ΔT = 0.308°C

As we know,

⇒

By substituting the values, we get

1) Proportions decreased as it reacted with other elements to form nitrogen. -AMMONIA

2) Proportions decreased as this lighter gas was blown away by solar winds.- HYDROGEN

3) Proportions increased as this gas was released through volcanic eruptions. -WATER VAPOR

4) Proportions increased as plants released this gas into the atmosphere.- OXYGEN

5)Proportions decreased as plants used this gas during photosynthesis.- CARBON DIOXIDE
