Explorando la energía y el calor: midiendo la energía calorifica

The video tutorial explains how to compare the heat energy of a cup of hot chocolate with a glass of ice water. It discusses the use of touch to sense temperature differences and introduces the thermometer as a precise tool for measuring heat energy. By observing the thermometer readings, it is evident that hot chocolate has a higher temperature and more heat energy than ice water.

Which of the following provides more heat energy?

• Neither provides heat energy

• Both provide the same heat energy

• A cup of hot chocolate

• A glass of ice water

What instrument can be used to measure the temperature of a liquid?

• Barometer

• Thermometer

• Hygrometer

• Anemometer

What does a thermometer measure?

• The color of a liquid

• How hot or cold something is

• The speed of an object

• The weight of an object

How can you tell which liquid has more heat energy by looking at a thermometer?

• By the color of the liquid

• By the height of the red line

• By the size of the thermometer

• By the shape of the container

What does a higher red line on a thermometer indicate?

• No change in temperature

• Higher temperature and more heat energy

• Equal temperature to other liquids

• Lower temperature and less heat energy
