Question

maya is helping her dad cook dinner. as he boils water for the pasta, he tells maya that once the water starts boiling, its temperature no longer increases because temperature stays constant during state changes. that seems strange to maya, so she decides to design an experiment to investigate temperature during state changes. she has the following supplies available: tap water, ice, olive oil, a heat - safe cup, a hot plate, a freezer, a thermometer. using only these supplies, which questions can maya investigate with an experiment? select all that apply. does tap water boil faster when salt is dissolved in it? does tap waters temperature stay constant as it boils on a hot plate? does ices temperature change as it melts? does olive oils temperature stay constant as it freezes?

Explanation:

Step1: Analyze each option

• For "Does tap water boil faster when salt is dissolved in it?": With tap - water, a hot plate, and a thermometer, Maya can conduct an experiment. She can measure the time it takes for plain tap - water to boil and then the time it takes for tap - water with salt dissolved in it to boil.
• For "Does tap water's temperature stay constant as it boils on a hot plate?": Using tap - water, a hot plate, and a thermometer, she can monitor the temperature of the boiling water over time.
• For "Does ice's temperature change as it melts?": With ice, a heat - safe cup (to hold the ice as it melts), and a thermometer, she can measure the temperature of the ice as it melts.
• For "Does olive oil's temperature stay constant as it freezes?": With olive oil, a freezer, and a thermometer, she can measure the temperature of the olive oil as it freezes.

Answer:

Does tap water boil faster when salt is dissolved in it?
Does tap water's temperature stay constant as it boils on a hot plate?
Does ice's temperature change as it melts?
Does olive oil's temperature stay constant as it freezes?
