Struggling with heat problems in your physics class? Our article is here to help! Packed with solved examples specifically designed for high school students, this guide will make mastering heat problems easy.
Both scales start at 0 ° ° for freezing, so we can create a simple formula to convert between temperatures on the two scales.
The temperature of an object can be measured using a thermometer which is based on a suitable thermometric property. (i) What is heat? (ii) What is meant by temperature? (iii)Give an example of a thermometric property. (iv) The SI unit of temperature is the kelvin. Give another temperature scale.
Observe heat transfer and change in temperature and mass. Calculate final temperature after heat transfer between two objects.
Calculate the energy transferred for each of these: 1. m = 0.5 kg and Δθ = 20 °C (for copper) 2. m = 2 kg and Δθ = 60 °C (for oil) 3. m = 40 kg and Δθ = 7.5 °C (for water) 4. m = 1.2 kg and Δθ = 0.5 °C (for air) 5. m = 2 kg and Δθ = 8 °C (for aluminium) 6. Challenge: m = 1 500 000 g and Δθ = 0.2 °C (for iron) 4 Material ...
We use the equation for heat transfer for the given temperature change and masses of water and aluminum. The specific heat values for water and aluminum are given in the previous table. Solution to (a)
We use the equation for the heat transfer for the given temperature change and mass of water and aluminum. The specific heat values for water and aluminum are given in Table \(\PageIndex{1}\). Solution. Calculate the temperature difference: \[\Delta t = T_f - T_i = 60.0^oC.\] Calculate the mass of water.
