Explanation / Answer

1.

Use equation,

°C = (°F - 32)*5/9 =(92 - 32)*5/9 = 33.33 oC

2.

Use equation

K= °C + 273.15 = -20 + 273.15 = 253.15 K

3. Use equation

K= (°F+ 459.67)*5/9 = (-16 + 459.67)*5/9 = 246.5 K

4. Electrocardiogram

An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart's electrical activity as line tracings on paper. The spikes and dips in the tracings are called waves. The heart is a muscular pump made up of four chambers .

5.

Fluids

6. 300K

Room Temperature = 27

K= 27 + 273 = 300 K
