How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object.
Historically the specific heat was related to SH of water .
Water being 1 That now is seen as archaic.
The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered.
Every substance has to be measured separately .

What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
How is mass related to the amount of heat in an object?
Strictly speaking objects do not contain "heat". Heat is energy in transit - think of it as an analog to water compared to rain. Rain is water in transit from the clouds to the ground. Once it lands and starts to form puddles, rivers, streams, etc, we no longer call it rain. Likewise, when energy is being held in an object we do not call it heat. It only becomes HEAT when in transit from that object to another object. What the question is probably trying to ask is about the relationship between the mass of an object and the enthalpy (or alternatively internal energy). As energy (such as heat) is added to an object, it gets warmer and the enthalpy increases. If it comes in contact with something cooler, it can transfer some of that energy in the form of heat, but the temperature can also be changed by doing work on the object or subjecting to friction. One property of any object is its "heat capacity" which is measured in terms of the amount of energy required to raise the temperature of the object by a certain amount. Usually this is identified in terms of the "specific heat" - the energy per unit mass per degree of temperature. As an example, the specific heat of liquid water is about 1 BTU per lbm per °F or 1 calorie per gram per °C at room temperature. The enthalpy of an object is thus related to the mass of the object via the specific heat. Note that enthalpy must always be measured relative to a reference point. It is what is known as a "state function". Typically the enthalpy is tabulated relative to a reference state of "standard temperature and pressure".
Does water heat up faster than water?
no, specific heat will always be 4.16
What is the formula to find specific heat of water Q?
The formula to find the specific heat of water ( Q ) is: ( Q = mc\Delta T ), where (m) is the mass of the water, (c) is the specific heat capacity of water, and ( \Delta T ) is the change in temperature of the water.
Why is a measured amount of water needed to determine the spicific heat of a metal object?
A measured amount of water is used in determining the specific heat of a metal object because water has a well-defined specific heat capacity (1 calorie/gram °C) and is readily available. By measuring the temperature change of a known mass of water when a metal object is immersed in it, and knowing the specific heat of water, we can calculate the specific heat of the metal object.
How do you determine the specific heat capacity of an object by method of cooling?
To determine the specific heat capacity of an object by the cooling method, you would first heat the object to a known temperature and then immerse it in a known volume of water at a lower temperature. By monitoring the temperature change of the water and the object over time, you can calculate the specific heat capacity of the object using the formula q = mcΔT.
Why is a measured amount of water needed to determine the specific heat of a metal object?
Because the heat energy absorbed or released by the water is dependent on the mass of the water. q=m x c x delta T The equation tells you that you need a mass, a specific heat and a change in temperature to figure out the specific heat of the metal.
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.
How is specific heat related to thermal heat?
specific heat is the amount of thermal energy needed to raise the temperature of an object. for example, the water on the beach and the sand on the shore are absorbing the same amount of thermal energy from the sun but the water (which has high specific heat) is cold, and the sand (with low specific heat) is very hot.
What constant is needed to determine the energy needed to warm the water to 25.C?
The answer is SPECIFIC HEAT!
How do you determine specific heat for sodium without water?
To determine the specific heat of sodium without water, you can use methods such as calorimetry or differential scanning calorimetry. In these methods, you would measure the temperature change of a known mass of sodium as it absorbs or releases heat energy. By measuring the temperature change and knowing the amount of heat energy involved, you can calculate the specific heat capacity of sodium.
How could you determine the specific heat of a sample of a solid substance that does not react with water?
One way to determine the specific heat of a solid substance that does not react with water is by using the method of calorimetry. This involves measuring the temperature change of the substance when it is heated or cooled, and using the formula q = mcΔT to calculate its specific heat capacity, where q is the heat added or lost, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change.
Describe how you could determine the specific heat of a metal?
You would do a calorimetry experiment. There are a number of ways to do this depending on what type of material you have. Essentially, you add a known amount of heat to an object, and you measure the temperature change (the mass of the object must be known, and also it must be as well insulated as possible.See the Web Links for more information about calorimetry experiments.joules_____________(celcius)(grams)
What effect does specific heat have on how easily an object changes temperature?
The higher the specific heat of an object, the more energy it requires to change its temperature. Objects with higher specific heat values require more heat input to increase their temperature compared to objects with lower specific heat values.
Which has the greater specific heat capacity- an object that cools quickly or an object of the same mass that cools more slowly?
The object that cools more slowly would have the greater specific heat, because the amount of heat that is needed to raise the temperature of it one degree is less than the amount of heat needed to raise the temperature of the first object one degree. i.e. the object that cools quickly does so because it doesn't need a lot of heat to increase the temperature of it by one degree and the one that cools more slowly does so because it needs more heat to increase the temperature of it by one degree.
The transfer of heat from moving water or r air to an object is?
The transfer of heat from moving water or air to an object is known as convection. This occurs when the air or water moves past the object, carrying heat energy with it and transferring it to the object. Convection can either cool or heat the object, depending on the temperature of the surrounding medium.
