Beryllium has roughly one-half the specific heat of liquid water (H2O). Rank the quantities of energy input required to produce the following changes from the largest to the smallest. In your ranking, note any cases of equality. (Use only the symbols > or =, for example a>b=c) (a) raising the temperature of 1 kg of H2O from 20°C to 26°C (b) raising the temperature of 2 kg of H2O from 20°C to 23°C (c) raising the temperature of 2 kg of H2O from 1°C to 4°C (d) raising the temperature of 2 kg of beryllium from -1°C to 2°C (e) raising the temperature of 2 kg of H2O from -1°C to 2°C

Step 1
The amount of heat required to raise the temperature of a substance is given by the formula Q = mcΔT, where m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Show more…
