Because it is easier to calculate an item in its solid form then in its liquid state. If you burn a metal on a burner, eventually it will melt making it harder to measure.This previous answer is not much help to you & I will give you another answer. The definition of Specific Heat is :- the number of Calories of heat energy required to raise the temperature of 1 gram of any substance , by an amount of 1Centigrade Degree. A century or more, ago, it was decided by scientists that they would use pure water as a control standard for Specific Heat . To raise the temp of 1gram of pure water 1centigrade degree, the amount of heat required was given the name Calorie. So, the S.H. Of Water is 1 Cal/ gram/ degree C. When we say that the S.H. of pure Copper is 8.93 Cal/gram/degreeC , this indicates to us that Copper needs heaps more heat energy to achieve what we achieve with Water. Substances with a large S.H. 'soak up' heat to a greater degree than water. Water was chosen as a standard substance with which we compare other less common substances. For the same reason as we chose water to graduate thermometers, with zero as freezing temperature and 100 as boiling temperature . Water is the most common substance used by people and is the same all over the entire world. Now, to answer your real question. Water is not needed to determine Specific Heat (S.H.) Water is used as the basis upon which S.H.of all other substances are compared Some values of S.H. for other substances. Iron 7.8 Glass 2.7 Alumimium 2.7 Wood 0.7 And in all these examples the 'unit' of S.H. Is always, Calorie per gram per degree Centigrade

Shiny objects that reflect light?
Metal has a metallic luster and is a conductor.
Is shortening metal a physical or chemical change?
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
What changes do you see when hot metal is cooling?
The metal object would contract, i.e it would shrink.
Can you use ever-silver utensils in microwave oven?
No metal object should be used in a microwave.
What is a good hypothesis for a hovercraft?
i think a good project would be seeing if the speed of the craft is affected by the weight of the person or object on it
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.
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.
What is this metal object on your dorm wall?
In order to know what a metal object is on a dorm wall one would need more information. If a description of the metal object is given one may be able to determine what the object is.
How do you determine if an object is metal?
if the element donates electrons then it is called a metal. eg. sodium, iron,etc.
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 experimental method can determine the density of metal?
Density is the mass of the object divided by its volume. By this principle, to determine the density of a metal, place the metal onto a scale to measure its mass. After this, place the metal into a beaker of water and measure the volume change in the beaker. Divide the mass by the volume and you get the density.
Does radar determine the size of an object?
Radar is usually used only to determine where something is, not how large it is, because the strength of the reflection depends upon the reflectivity of the surface, the distance of the object, and the size of the object; a large wooden object can return less of a signal than a much smaller metal object, for example. It's too complicated a problem. But if you already know that you are looking, let us say, for an airplane, then radar is very good at showing you where the plane is.
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)
How does density and mass make a metal?
The density of a metal is a measure of how tightly packed its atoms are. Mass is a measure of the amount of matter in an object. Together, density and mass determine the physical properties and behavior of a metal, such as its weight, strength, and conductivity.
When you rub a magnet with metal what happens to the metal object?
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
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 .
Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to determine which block will increase its temperature t?
To determine which block will increase its temperature the most, compare the specific heat capacity of each metal. The metal with the lowest specific heat capacity will increase its temperature the most with the same amount of heat energy absorbed. Choose the metal with the lowest specific heat capacity among the four blocks.
