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)
Both scales start at 0 ° ° for freezing, so we can create a simple formula to convert between temperatures on the two scales.
Observe heat transfer and change in temperature and mass. Calculate final temperature after heat transfer between two objects.
9 Ιαν 2021 · Solution: Initial and final temperatures are $T_i=50.4^\circ$ and $T_f=25^\circ$, respectively. Applying the specific heat equation and substituting the numerical values, we get \begin {align*} c&=\frac {Q} {m\Delta T}\\ \\&=\frac {47\, {\rm cal}} {1\, {\rm g} (50.4-25)}\\ \\ &=1.850\quad {\rm cal/g\cdot K}\end {align*}
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.
