, Do the three conversions shown below, showing all work:
1. 328 K = ? oC
2. 76oC = ? oF
3. 135oF = ? K
Your Answer:
1 - 328 - 273 = 55 C
2 - (76x 1.8) + 32 = 168.8 F
3 - (135 - 32) / 1.8 = 57.2 C + 273 = 330.2 K
1. 328K - 273 = 55 oC K → oC (make smaller) -273
2. 76oC x 1.8 + 32 = 168.8 oF o
C → oF (make larger) x 1.8 + 32
3. 135oF - 32 ÷ 1.8 = 57.2 + 273 = 330.2 K o
F → oC →K
