Tom wanted to test his hypothesis that plants grow better at room temperature than in cold temperatures. he placed an ivy plant in the refrigerator, which had no light source. he also placed a spider plant in the window in his room. what were tom's variables?

The answer is the refrigerator and window.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
