Specific Heat

What is Half-life?

• The amount of time it takes for some of the nuclei in a sample of the isotope to decay
• The amount of time it takes for half the electrons in a sample of the isotope to decay
• The amount of time it takes for half the nuclei in a sample of the isotope to decay
• the amount of time it takes to double the nuclei in a sample of the isotope to decay

There are four cups of hot cocoa. The cup sizes are shown. The temperature of the cocoa in each cup is 25 degrees celsius. Which cup has the MOST thermal energy?

• Largest cup (Trenta)

• Small cup (Tall)

• Venti

• All three are the same temperature so they have same thermal energy

If the specific heat of water is 4,184 J/g∙°C, how much heat is required to increase the temperature of 1200 g of water from 23 °C to 39 °C?

• -80,371.2 J

• 44,938.6 J

• 80,371.2 J

• 112,575.9 K
