A boy and his younger sister are at the zoo on a hot day. They each buy a cold lemonade. The boy buys a large lemonade, and his sister buys a small. They set their cups on a hot table and wait a while before they start drinking. When they finally begin to drink their lemonade, The girl complains that her drink is no longer cold. However, the brother states that his larger drink is still cold. Which of the following Statements best explain why the boy's drink is still cold but the girl's drink is not?

• The large cup of lemonade has more particles and requires more energy from its surrounding to warm up.
• The large cup of lemonade has more particles and requires less energy from its surrounding to warm up.
• The small cup of lemonade has fewer particles and requires more energy from its surrounding to warm up
• Both cups of lemonade require the same amount of energy from their surroundings to warm up the same temperature.

A boy and his younger sister are at the zoo on a hot day. They each buy a cold lemonade. The boy buys a large lemonade, and his sister buys a small. They set their cups on a hot table and wait a while before they start drinking. When they finally begin to drink their lemonade, The girl complains that her drink is no longer cold. However, the brother states that his larger drink is still cold. What conclusions could the boy and girl accurately draw from their observations?

• Energy from the hot table and warm air is transferred to the cold cups of lemonade.
• The thermal energy of a liquid is the same regardless of its size.
• If there are two different amounts of the same liquid, the temperature is a good way to compare their thermal energies.
