For 2 kg and an entered specific heat of 1,000 J/(kg·K), a 10 °C temperature increase requires 20 kJ. The same decrease gives −20 kJ.

Sensible heat = mass × specific heat × (final temperature − initial temperature)

Enter these known values and leave the other values blank.

Mass and specific heat are positive. Specific heat is constant over the entered temperature interval.
This model includes sensible heat only. It excludes phase-change energy, reaction energy, heat losses and heating of containers.
Material presets are illustrative constant values, not temperature-dependent property tables. Use a suitable measured or published value for your material and conditions.
Positive heat means heat added; negative means removed. Temperature differences use interval conversions, so 10 °C change equals 18 °F change.
Initial and final temperatures must exceed absolute zero.

Yes. Set the final temperature below the initial temperature. The heat result is negative under the heat-added convention.

No. This constant-specific-heat model excludes phase changes and their latent heat.

Calorie-based specific heats use the thermochemical calorie, exactly 4.184 joules, consistently with the heat-capacity units.
