GCSE AQA Combined Physics Paper 1 RPAs

In the Specific heat capacity RPA, what is the independent variable?

• The temperature change

• The mass of the block (material)

• The Energy change

• The material being heated

In the specific heat capacity RPA, what is the dependent variable?

• The material being heated

• The energy change

• The mass of the block

• The specific heat capacity

RPA 1: What is the correct formula to calculate energy change?

• Energy change = mass x specific heat capacity x temperature change

• Mass = energy change x specific heat capacity x temperature change

• Specific heat capacity = mass x temperature change x energy change

• Temperature change = mass x specific heat capacity x energy change

What is the standard S.I. unit for mass?

• Newtons

• Grams

• Kilograms

• Joules

RPA1 : which instrument is used to measure the mass of the blocks?

• A newton gauge

• A top-pan balance

• A joule-meter

• An accelerometer

RPA 1 (Specific heat capacity) What instrument is used to measure the change in temperature?

• A joule-meter

• A voltmeter

• A multimeter

• A thermometer

RPA 1 (SHC): The temperature change = ...

• The initial temperature

• The final temperature

• Initial temperature - final temperature

• Final temperature - initial temperature

RPA 1 (SHC): The energy change is recorded on...

• A voltmeter

• An ammeter

• A joule-meter

• A stopclock

RPA 1 (SHC): A student records the following results:

Mass of block = 2.0 kg

Energy change = 20,000J

Temperature change = 40 degrees celsius

What is the specific heat capacity of the material she tested?

• 100 J/kg degrees C

• 250 J/kg degrees C

• 400 J/kg degrees C

• 500 J/kg degrees C

RPA 1 (SHC) : The temperature change measured is usually lower than the expected amount. This is because...

• The student recorded the temperature inaccurately

• The student used a lower powered heater

• The material was not insulated

• The timer had an error
