Specific Heat Capacity Practical

When you forget to tare a weighing scale with a beaker on before measuring the mass of a powder, you make

• A random error
• An anomalous result
• A systematic error
• A fool of yourself

The unit of Specific Heat Capacity is

• Kilogram per Joule per Celsius degree
• Joule per kilogram per Celsius degree
• Celsius degree per Joule per kilogram
• Kilometre

What is the independent variable

• Anything that can change

• The thing you change

• The thing you measure at the end

• The thing you keep the same

What is the dependent variable

• Anything that can change

• The thing you change

• The thing you measure at the end

• The thing you keep the same

What is a control variable

• Anything that can change

• The thing you change

• The thing you measure at the end

• The thing you keep the same

A prediction is...

• ... just a lucky guess

• ... what you think will happen and why

• ... an estimate

What does this define: To find the ______, order the numbers and see which one is in the middle of the list.

• median

• mode

• range

• mean

What is a variable

• Anything that can change

• The thing you change

• The thing you measure at the end

• The thing you keep the same

Why is the main source of error in the calculation of the specific heat capacity in this investigation?

• reading the thermometer

• you can have different metals

• measuring the time on the stop clock

• heat loss to the surroundings

Some of the energy will heat up the surroundings rather than going into the metal you are testing. How does this affect your calculation of the specific heat capacity?

• the calculated specific heat capacity is accurate

• the calculated specific heat capacity is higher than it should be

• the calculated specific heat capacity is lower than it should be
