The amount of heat needed can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass (5g), c is the specific heat (2 J/g°C), and ΔT is the temperature change (10°C). Plugging the values into the formula gives Q = 5g * 2 J/g°C * 10°C = 100 J. Therefore, 100 Joules of heat must be added.

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?
A substance with a lower specific heat will warm more than a substance with a higher specific heat when the same quantity of heat is added. This is because substances with lower specific heat require less energy to increase their temperature compared to substances with higher specific heat.
What is the relationship between energy and temperature change?
Energy is required to change the temperature of a substance. When energy is added to a substance, its temperature increases, and when energy is removed, its temperature decreases. This relationship is governed by the specific heat capacity of the substance.
How will the substance change if energy is added to the liquid at 20 degrees celsius?
Adding energy to a liquid at 20 degrees Celsius will increase its temperature, causing it to heat up. As it reaches its boiling point, the liquid will undergo a phase change and turn into a gas.
Why may the temperature of a substance change when energy is added?
When energy is added to a substance, the temperature can change because the molecules in the substance gain kinetic energy, causing them to move faster. This increased movement leads to a rise in temperature. Conversely, if energy is removed from a substance, the temperature may decrease as the molecules lose kinetic energy and slow down.
Is there any experiment that you can do to determine the specific heat capacity?
One experiment to determine specific heat capacity is the method of mixtures. This involves heating a known mass of a substance, such as water, and then transferring it to a calorimeter containing a known mass of a different substance at a different temperature. By monitoring the temperature change in the system, you can calculate the specific heat capacity of the substance.
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.

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 heat is added to ice, the ice absorbs the energy and starts to melt into water. The ice-water mixture remains at 0 degrees Celsius until all the ice has melted. Once all the ice has melted, the temperature of the water will begin to rise.
What edible substance can be added to food to make it freeze at a lower temperature?
salt
