What instrument is used to measure temperature?

• Thermometer

• Anemometer

• Hygrometer

• Barometer

What are the three main states of matter?

• solid, liquid, plasma

• solid, liquid, gas

• gas, liquid, crystal

• plasma, vapor, foam

How does temperature affect the state of matter?

• Higher temperatures always lead to solid states.

• Temperature only affects gases, not liquids or solids.

• Temperature influences the state of matter by changing the energy and movement of particles, leading to phase transitions.

• Temperature has no effect on the state of matter.

Define specific heat capacity.

• Specific heat capacity is the total energy contained in a substance.

• Specific heat capacity is the temperature at which a substance changes state.

• Specific heat capacity is the mass of a substance divided by its volume.

• Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

What is the formula for calculating heat energy?

• Q = mΔT

• Q = mc^2

• Q = mcΔT

• Q = mgh

What is thermal conductivity?

• Thermal conductivity is the measure of a material's density.

• Thermal conductivity is a measure of a material's ability to conduct heat.

• Thermal conductivity refers to the temperature of a material.

• Thermal conductivity is the ability of a material to insulate against heat.

Which material is a good thermal conductor?

• Glass

• Wood

• Plastic

• Copper

What is the difference between conduction and convection?

• Conduction occurs in gases, while convection occurs in solids.

• Conduction is faster than convection in all cases.

• Convection requires direct contact between materials, while conduction does not.

• Conduction transfers heat through solids, while convection transfers heat through fluids.

How does heat transfer occur in liquids?

• Heat transfer in liquids happens exclusively through diffusion.

• Heat transfer in liquids occurs only through conduction.

• Heat transfer in liquids occurs mainly through convection.

• Heat transfer in liquids is primarily due to radiation.

What is calorimetry used for?

• Calorimetry is used to measure heat transfer in chemical reactions and physical changes.

• Calorimetry is used to determine the density of liquids.

• Calorimetry is used to measure the color of substances.

• Calorimetry is used to analyze the pH levels in solutions.
