Question

does the following text have an inappropriate shift in verb tense? if so, fix any verbs that dont match the tense of the verb in bold. if not, submit the text without making any changes.

in her chemistry demonstration, kayla showed that at sea level, water without impurities boils at 100°c.

Explanation:

The verb "showed" is in the past tense. However, the statement "water without impurities boils at \(100^{\circ}C\)" is a general scientific fact. General facts are typically expressed in the present tense. So, there is an inappropriate shift in verb tense.

Answer:

In her chemistry demonstration, Kayla showed that at sea level, water without impurities boils at \(100^{\circ}C\).
