SkillrHub Test guide

Each attempt draws five questions from the full bank. Repeat an attempt to meet more questions.

Worked model: Two equal containers each start with 100 mL. After a warm day, the open one has 76 mL and the covered one 96 mL. Neither leaked. What is supported?

Worked answer: The cover reduced water loss in this comparison. The open container lost 24 mL and the covered one 4 mL. The cover reduced loss under these conditions; the result does not prove zero evaporation.

Check your reasoning: Compare each final amount with its starting amount.
