IS it true that different materials need the same amount of heat to have similar changes in temperature?

No, they require different amounts of heat. For example, 100 g of water requires more energy (heat) to be raised from 0 degrees to 25 degrees than 100 g of iron does. This has to do with specific heat/heat capacity.

Two types of variable in science?
The two broad types of variables in scientific experimentation are dependent and independent variables. Independent variables are variables (ideally only one or very few) that the experimenter manipulates in the experiment. For example, if you were testing the effect of temperature on plant growth rates, you would likely have similar plants in similar conditions but in areas with different temperatures. The experimenter is changing the temperature between the groups of plants, so the temperature would be the independent variable. The dependent variables are the effects the independent variable has on the experimental subjects. They are changes not being directly controlled or manipulated by the experimenter. In the above temperature vs. plant growth example, the rate of plant growth would be the dependent variable; it depends on the temperature.
What is an independent experiment?
In general, it is an experiment that is run by different experimenters, using different-but-similar equipment, in a different locale, and perhaps a different-but-similar testing protocol.
In your opinion were European and Japanese societies more similar to or different from each other?
In my opinion they were similar in some ways but different in others.
What is the use of tirril burner?
It is similar to Bunsen burner. It is used for high temperature burning.
How are the states changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Which temperature scale is not directly or indirectly based on a phase changes in water?
Fahrenheit Scale is the temperature scale that is not directly or indirectly based on the phase changes in water. Another similar temperature scale is Celsius Scale.
Why would changes occur to similar spices on different islands?
Well the temperature, the amount of sunlight, the amount of water, the quality of the soil , and the quality of the air would all affect this.
How is the sun different in size and temperature from a star?
It isn't. The sun is a star and there are others that are similar in size and temperature.
How are physical and chemical changes affected by temperature?
Chemical reactions involve changing the materials that you're dealing with into new materials, and the changes that you see are the result of the appearance of the new materials. The new material might have a different phase than the starting materials. For example, if you create something new from two liquids and it happens to be a gas, then you will get gas bubbles. There will be a new material with a new phase that wasn't there before. Also, you can observe chemical reactions by seeing color changes, if the new material has a different color than the starting materials. When a chemical reaction takes place, usually the temperature will also change. It will either go up or down, sometimes imperceptibly. Those are the kinds of changes that you might see. In chemical reactions the changes that you observe are caused by the creation of or loss of different kinds of materials. Physical changes are similar in some ways because you are looking at the same kinds of things--changes in the phase, the color, the temperature. But the physical changes are changes in the condition of the material or changes caused by mixing materials together or taking them apart--just mixing or separating, not the creation of something new. For example, temperature changes are physical changes if they are caused by heating or cooling. If you add heat to something and the temperature goes up, that is a physical change. If you cool it off and the temperature goes down, that is a physical change. Phase changes are physical changes also, if they are caused by heating or cooling. If you take some water and you heat it up and it changes to gas, that is a physical change. You still have water, only now it is steam instead of liquid. Also included in physical changes are color changes that are caused simply by mixing or by diluting a material or, in some cases, even by heating. For example, if you turn on an electric range and the element gets hot, you can see a color change. That is also a physical change. Physical changes and chemical changes have much in common in that you are looking at similar kinds of results. The difference is whether the appearances or differences that you see are from a change in the condition of the material or from a change in what materials are present. That's the kind of thing you need to look for to distinguish between a chemical reaction and a physical change. It takes an inference to make that distinction. Sometimes it is very difficult to make that distinction and in some cases even chemists can get into arguments sometimes over what constitutes a physical or a chemical change. For example, when salt dissolves in water, some people say that is simply a physical change because if you evaporate away the water, you have the salt back again. Other people argue that there is a chemical change because the material present in solution has different properties than the separated pure water and pure salt. The solution will conduct electricity and the pure water and pure salt will not. So, there are cases where the distinction between physical and chemical changes gets kind of blurred. In a few weeks we will have more criteria we can use to distinguish between physical and chemical changes.
Why can humans almost anywhere in the world?
because when there present area temperature changes from cold to hot or sometimes different then it did the first time many times the get used to it, so when the go to a place with similar temperature they don't get too hot or too cold because there already use to it.
How are thermal energy and temperature similar and different?
Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement.
Is bromine a substance?
Yes it is a substance. A brown liquid that changes to a brown gas at less than room temperature.. It i similar to chlorine.
How does the rate of chemical and physical change differ around the world?
In similar conditions (temperature, pressure, inatallations, materials, etc.) a difference doesn't exist.
Would you expect to see similar changes in heart rates in human cardiac muscle and frog cardiac muscle with environmental temperature changes?
No. Frogs are not mammals nor endothermic, which is why they change their heart rate and temperature to match their surroundings. Humans regulate their body temperature and heart rate at a steady rate no matter what their surroundings are.
Why do flames colored?
Well simple, It's similar to the way light changes colors when it's refracted through different materials, such as a rainbow. After rain, the sunlight is bent through the humid atmosphere causing colors. same with fire, different substances used in its firelighter (aka Ligherfluid) change colors of the flame itself
Which two planets are most similar in temperature?
Jupiter and Neptune are the most similar in temperature.
Does argon have similar properties to chlorine?
No. Other than both being gasses at room temperature they are quite different.
