At 9: 00 a. m. monday morning, thomas fills a beaker with water and places it in the corner of the classroom. at 1: 00 p. m. on tuesday, thomas examines the beaker and notices that the water level is 42 milliliters. at 11: 00 a. m. on wednesday, the water level has dropped to 31 milliliters. if the evaporation of the water follows a linear function, at what time will the beaker be empty? .

Answer is: will the beaker be empty Saturday 1:00 am.

l₁ = 42 mL; water level at Tuesday.

l₂ = 31 mL; water level at Wednesday.

Δl = l₁ - l₂.

Δl = 42 mL - 31 mL.

Δl = 11 mL; difference between water levels.

Δt = 22 h; difference in time.

rate of evaporation = Δl ÷ Δt.

rate of evaporation = 11 mL ÷ 22 h.

rate of evaporation = 0.5 mL/h.

t = 31 mL ÷ 0.5 mL/h.

t = 62 h; time needed for empty the beaker.
