Question

i really need help :( please help??!!
problem 1: Conditions for an experimental chemistry reaction require a temperature of 298 K. The temperature in the lab is 55°F. Which of the following must you do to meet the requirements? (°F= 9/5 (K - 273) + 32)
A. increase the room temperature by 22°F
B. decrease the room temperature by 12°C
C. decrease the room temperature by 33°F
D. increase the room temperature by 18 K
**Idk :( please help!!

Answer 1

#2: Jim, Jane, Ann, and Bill measure an object’s length, density, mass, and volume, respectively. Which student’s measurement might be in liters?

A. Bill’s

B. Jim’s

C. Jane’s

D. Ann’s
**My answer: A. Bill's
is this one right?

Answer 2

1. (°F= 9/5 (K - 273) + 32)

K=298

plug into formula.. compare to 55.. you should be able to do this simple arithmetic

Answer 3

2. you are right, volume is measured in liters, or in a measurement of length cubed. eg. cm^3 which equals 1 mL.

Answer 4

so #1 is this?? 9/5(298-273)+32=77
so increases by 22 degrees.
so my answer to #1 is this??
A???

and #2 yay :)
