∙ 10y agoHeat energy= mass*specific heat*change in temperatue
Hence,Specific heat=10/4=2.5kcal/kgC

How will the substance change if energy is added to the liquid at 20 degrees celsius?
the substance will get hotter.
What happens to temperature as energy is added to a substance that is changing state?
The temperature remain constant during the phase changing.
When the same quantity of heat is added per unit as does a substance having a lower specific heat warm more or less than a substance having a higher specific heat?
specific quantity
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
Why would the temperature of a liquid remain constant when heat is continuously being added?
A temperature at which internal pressure become equal to atmospheric pressure is called boiling pointAt boiling point kinetic energy of liquid molecules remains constant ,although heat is continously supplied that is why boiling point of a liquid remains constant.
The specific heat of substance A is greater than that for substance B If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these s?
The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these samples, substance A will have a lower temperature than substance B.
What is the specific heat of benzene if 3450J of heat is added to 150.0 g sample of benzene and its temperature increases from 22.5 degrees celsius to 35.8 degrees celsius?
1.7293
How will a substance change if energy is added to the liquid at 20 degrees Celsius?

What is the being added or removed when a substance temperature changes?
HEAT
What is being added or removed when a substance's temperature changes?
heat
What is the temperature of ice when salt is added to it?
38 degrees
Suppose a fixed number of joules of energy as heat is added to 1 kg of substances listed below. Which substance will the rise in temperature be the least?
The greater the specific heat, the lower the temperature rise. The specific heats will be listed in the Handbook of Physics and Chemistry.
What temperature does a phase change begin?
It will start to melt if the temperature rises above 0 degrees Celsius or 32 degrees FahrenheitOfficially, the melting temperature of ice is zero degrees Celsius (or 32F). The freezing temperature does vary dependent on the electrolytes added to the water solution. For example, ocean water (salt water), freezes at ~-18 degrees Celsius (or 0F). Various solutions at different concentration of solute offer various degrees of melting/freezing. At 0 degrees Celsius.
What are the steps when heat is added to ice?
When any substance is heated, the temperature rises.
What edible substance can be added to food to make it freeze at a lower temperature?
salt
