300
Define thermal energy.
the total amount of energy of all particles within an object
300
Describe what happens to the particles that make up an object when it is heated.
they move faster and move further apart from each other
300
This movement of fluid occurs when it is being heated, the second word is also used in electricity.
Convection Current
300
If a circuit only has one conducting pathway, is it series or parallel?
Series
300
This letter is used as the symbol for current, not the unit amperes (that uses the letter A).
What is I?
400
What is JoJo Siwa's real name?
Joelle Joanie Siwa
400
Define thermal equilibrium.
When two objects in contact are the same temperature, so no thermal energy flows between them.
400
State what temperature measures?
Temperature indicates how hot or cold something is, the average kinetic energy of a sample
400
This method of heat transfer occurs when cooking solid food in a frying pan.
Conduction
400
Identify whether this circuit is series or parallel.
Parallel
400
Is voltage, current or resistance the rate of flow of electrical charge?
Current (I)
500
Who is the most followed person on Instagram?
Cristiano Ronaldo
500
Define a conducting pathway.
Path which allows charge to flow from one terminal of battery to another
500
Describe what happens to the temperature when a stack of cups are placed into a sink of hot water.
The water has a higher thermal energy and will transfer heat to the cups. The cup gains thermal energy from the water until they are the same temperature.
500
Explain how convection heats us water in a pan.
When a saucepan is heated, the water at the bottom gets hot first. The hot water particles move faster and spread out, making them less dense. Because of this, the hot water rises. Cooler, denser water from the top sinks down to take its place. This creates a circular movement called a convection current, which spreads the heat through the whole pan of water.
500
State the direction of electrical current, (is it from + to - or - to +).
- to +
500
According to Ohm's Law, V=IR. Calculate the voltage of a 4 ohm resistor with 5A current running through it.
V= 4x5 =20 V
