Answers. = mc∆T, where Q = heat energy, m = mass, and ∆T = change in temp. Remember, ∆T = (Tfinal – Tinitial). Show all work and proper units. A 15.75-g piece of iron absorbs 1086.75 joules of heat energy, and its temperature changes from 25°C to 175°C. Calculate the specific heat capacity of iron.
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)
Observe heat transfer and change in temperature and mass. Calculate final temperature after heat transfer between two objects.
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.
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*}
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 ...
