Thermal Equilibrium
Test - In order to make iced tea Lois brings a pitcher of water to a boil, adds tea and then ice to cool the tea. Which of the following best describes the direction of of the flow of thermal energy
the energy flows from the tea to the ice
the energy flows from the ice to the tea
the energy flows between the ice and the air equally
the energy flows between the ice and the tea equally
Test - What would happen if a 20 degree ball is placed inside a 30 degree box
energy will flow from the ball into the box until they come to the same temperature at 50 degrees
energy will flow from the box into the ball until they come to the same temperature at 25 degrees
energy will flow from the ball into the box until the box decreases in temperature to 20 degrees
energy will flow from the box into the ball until the ball increases in temperature to 30 degrees
Test - Lindsay is boiling macaroni noodles in a pot of water. The noodles rise and fall as the thermal energy currents move from areas of higher energy to areas of lower energy. Which process is primarily responsible for making the macaroni noodles move in the boiling water
conduction
convection
radiation
evaporation
Test - Harvey is baking a pan of brownies to take to school. Which of the following best describes what types of energy transfer are responsible for transferring heat from the over to the brownies
convection and conduction
conduction and nuclear
conduction and radiation
convection and radiation
Test - As energy in the from of heat is added to an ice cube, it begins to melt. What causes melting?
the transfer of thermal energy to the ice cube causes it to melt
the transfer of thermal energy away from the ice cube causes it to melt
heat causes the molecules in the ice cube to expand and forces them apart
heat removes the thermal energy from the ice cube and causes it to become liquid water
Test - Maria sits on a park bench on a cold sunny day. The bench feels warm. What process transfers heat from the bench to Maria's body
conduction
motion
convection
radiation
Test - Transfer of thermal energy through space
conduction
convection
radiation
electromagnetic
Test - how is temperature related to heat
temperature is a measure of the heat of an object
heat causes a change in the temperature of an object
raising the temperature causes the heat of an object to increase
temperature and heat are two different ways to measure the same thing
Test - If one part of a solid object is a higher temperature and another part of the same object is at a lower temperature, the heat is transferred within the object through the process of
conduction
convection
insulation
radiation
Test - Lainey wanted to know how long it would take to convert ice into steam. She held the test tube with ice over open flame and recorded her observations in her lab journal. The image shows what she observed. Which statement below best explains Lainey's observations
water releases heat to the air causing the state of matter to change
heat was added causing the water to move through the states of matter
the rise in temperature caused the water to move through the states of matter
absorbing heat from the air allows the water to move through the states of matter
