The specific heat of any substance can be found by calculating the amount of heat required to raise a unit mass quantity of it by 1 degree. The relationship between heat and temperature change is Q=cm(change in T) where Q is heat in Joules, c is the specific heat, m is the mass, and T is the temperature.

What is the formula for finding the mass in specific heat?
The formula for finding mass using specific heat is: mass = (heat energy)/(specific heat x change in temperature). This formula is derived from the specific heat equation, q = mcΔT, where q represents heat energy, m is mass, c is specific heat, and ΔT is the change in temperature. By rearranging the equation to solve for mass, we can determine the mass of a substance based on the amount of heat energy supplied, the specific heat capacity of the material, and the resulting change in temperature.
If a substance has a specific heat less than one would it take more or less heat to raise the temperature?
If a substance has a specific heat less than one, it would take less heat to raise its temperature compared to a substance with a specific heat of one. This is because substances with lower specific heat values require less energy to raise their temperature by a certain amount.
Is a mixture of glycerin and potassium permanganate flammable?
A mixture of glycerin and potassium permanganate can be flammable. When glycerin comes in contact with potassium permanganate, a vigorous exothermic reaction can occur, producing intense heat and potentially igniting the surrounding materials. Extreme caution should be exercised when handling this mixture.
What are some common specific heat problems and how can they be solved effectively?
Common specific heat problems include calculating the amount of heat needed to raise the temperature of a substance, determining the final temperature when two substances of different temperatures are mixed, and finding the specific heat capacity of a substance. These problems can be solved effectively by using the specific heat formula Q mcT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature. By plugging in the known values and solving for the unknown, these problems can be successfully resolved.
Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
When a 290 g piece of iron at 1800C is placed in a 100 g aluminum calorimeter cup containing 250 g of glycerin at 100C the final temperature was observed to be 380C. What is the specific heat of glyce?
To find the specific heat of glycerin, we can use the principle of conservation of energy, where the heat lost by the iron equals the heat gained by the aluminum cup and glycerin. The heat lost by iron can be calculated using ( Q = m \cdot c \cdot \Delta T ), where ( m ) is the mass, ( c ) is the specific heat, and ( \Delta T ) is the temperature change. Since the final temperature is below the initial temperature of the iron, we can set up the equation and solve for the specific heat of glycerin. However, to provide an exact numerical answer, we would need the specific heat of iron and aluminum, which are typically around 0.45 J/g°C and 0.897 J/g°C respectively.
Is tannic acid and glycerin soluble in camphor solution?
It is! You just have to heat the glycerin!
What is flash point of glycerin?
The flash point of glycerin is approximately 160°C (320°F). This is the temperature at which glycerin can ignite if exposed to an open flame or heat source.
What is the formula for finding the mass in specific heat?
The formula for finding mass using specific heat is: mass = (heat energy)/(specific heat x change in temperature). This formula is derived from the specific heat equation, q = mcΔT, where q represents heat energy, m is mass, c is specific heat, and ΔT is the change in temperature. By rearranging the equation to solve for mass, we can determine the mass of a substance based on the amount of heat energy supplied, the specific heat capacity of the material, and the resulting change in temperature.
What is the formula in finding the amount of heat transfered to an object?
The formula for finding the amount of heat transferred to an object is Q = mc(change in T). Q represents heat energy in J, m is the mass of the object in kg, and c is the specific heat of the material.
Is good to put heat on your hair when you use glycerin?
Using heat on your hair while applying glycerin can enhance its effectiveness by helping the glycerin penetrate the hair shaft more deeply. However, it's important to use moderate heat to avoid damage, especially if your hair is prone to dryness or heat damage. Always ensure your hair is well-conditioned and consider using a heat protectant to minimize any potential harm. Balancing heat and hydration is key for maintaining healthy hair.
Does glycerin expire?
Glycerin has an indefinite shelf life if stored properly in a cool, dry place away from direct sunlight. Over time, glycerin may become less effective if exposed to heat or light, but it does not technically expire.
What is the formula for finding the final temperature in specific heat?
The formula for finding the final temperature in specific heat calculations is given by: [ T_f = T_i + \frac{Q}{m \cdot c} ] where (T_f) is the final temperature, (T_i) is the initial temperature, (Q) is the heat added or removed, (m) is the mass of the substance, and (c) is the specific heat capacity. This equation assumes no phase change occurs during the process.
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
What would be a good sentence for specific heat?
To be effective, this welding rod must be brought to a specific heat.
Would it be better to have pots and pans made from material with a high specific heat capacity or low specific heat capacity?
Higher Heat
Would two different liquids stored in the fridge for the same period of time be equally cold?
No. They would lose (or absorb) the same amount of heat, but their temperatures would be different.Every liquid has a unique specific heat capacity.The specific heat capacity of a substance is the amount of heat required to heat unit mass (1 kg) of that substance through 1°Celsius.So, liquids with different specific heats would show different change in temperature after losing the same amount of heat.For example, a liquid with a lower specific heat capacity would require lesser heat to change it's temperature while one with a higher specific heat capacity would require more heat.Hence, since the heat lost would be the same, the liquid with a lower specific heat capacity would cool more and have a lower temperature.
