Question

construct an explanation to answer this question: how does the lid affect what happens to the liquid in the cup? claim: state your argument clearly.(pick 1 claim from the list shown on the board) a cup with a lid causes a hot liquid in the cup to cool. evidence: write down your at least 2 - 3 observations/data from the cup lid lab 1 that your group did to support your claim. sentence starters: in the data... based on..., i think... the evidence i use... is... in the data from experiments where temperature was measured over time for a cup with a lid and without, the cup with a lid showed a slower rate of temperature decrease (due to reduced convection). based on the principle of conduction, the cup with a lid has less evaporation (as seen by less water - level decrease due to evaporation in a given time), and thus less cooling from evaporation. the evidence i use, such as comparing the temperature of a covered and uncovered cup of hot liquid at similar intervals, is that the covered cup (with lid) retained more heat. reasoning: how does this evidence support your claim? (explain what this data means) sentence starters: the reason i believe... is... based on the evidence, we must conclude that... because... all this proves that... because...

Explanation:

The claim is that a cup with a lid causes a hot liquid in the cup to stay hotter. The evidence includes data from experiments where temperature was measured over time for a cup with a lid and without. The cup with a lid showed a slower rate of temperature decrease (due to reduced convection). Based on the principle of insulation, the cup with a lid has less insulation loss (as seen by less water - level decrease due to evaporation in a given time) and thus less cooling from evaporation. The evidence used, such as comparing the temperature of a covered and uncovered cup of hot liquid at similar intervals, shows that the covered cup (with lid) retained more heat.

Answer:

A cup with a lid causes a hot liquid in the cup to stay hotter. In the data from experiments where temperature was measured over time for a cup with a lid and without, the cup with a lid showed a slower rate of temperature decrease (due to reduced convection). Based on the principle of insulation, the cup with a lid has less insulation loss (as seen by less water - level decrease due to evaporation in a given time) and thus less cooling from evaporation. The evidence used, such as comparing the temperature of a covered and uncovered cup of hot liquid at similar intervals, shows that the covered cup (with lid) retained more heat.
