A hot flame is a qualitative measurement, as it describes the subjective perception of the flame's temperature based on sensory experience rather than a precise numerical value.
There are three: Safety flame: The hole is closed. Orange flame. Not too hot, Blue flame: Hole half open. Almost invisible. Hot. Used for heating liquids, Roaring blue flame: Hole open. Very hot blue part inside lighter coloured part. Used for heating solids.
A yellow flame is typically called a reducing flame. This type of flame is often seen in gas stoves and burners where there is an imbalance of air and fuel, leading to incomplete combustion and producing a yellow color.
To test for monosaccharides, you would typically need basic laboratory equipment such as test tubes, a hot water bath or a Bunsen burner for heating, Benedict's reagent for reducing sugars, and glucose test strips for qualitative testing. Additionally, a spectrophotometer or a colorimeter may be used for quantitative analysis.
If you spray charcoal onto a non-luminous flame, the charcoal will burn due to the presence of oxygen in the flame. The heat from the flame will cause the charcoal to ignite and combust, creating a bright and hot flame.
Tongs or heat-resistant gloves should be used to remove a hot beaker from a flame to prevent burns. Never use your hands directly to handle hot items in a laboratory setting.
qualitative - smells of smoke, hot air from flame, flame is orange and blue at the bottom, flame moves around, [unscented candle - no smell], wick is burning and turning black. quantitative - sorry i don't have the answer. I'm looking for it myself :(
Quantitative means in measurable amounts as opposed to qualitative. For instance, if someone asked you what the weather was like you could say, "it is hot" (qualitative), or you could say, "it is 95 degrees" (quantitative).
Temperature is a measurement of the average kinetic energy of particles in a substance. Hot and cold are subjective terms used to describe the sensation of temperature relative to our bodies. Therefore, temperature itself is a quantitative measurement, while hot and cold are qualitative descriptors.
The statement "the temperature outside is 250°C" is quantitative. It provides a specific numerical value that can be measured and compared, indicating the precise temperature. In contrast, a qualitative statement would describe characteristics without numerical measurement, such as saying the temperature feels hot or cold.
The way I remember it is that Quantitative data includes quantities... numbers. 3.4 m, or 57 degrees Celsius Qualitative data describes qualities... descriptions. hot, blue, longer.
Qualitative descriptions are generally adjectives like 'cool' or 'hot' whereas quantitative descriptions are values like '35 degrees celsius'.
Temperature is a quantitative measurement because it involves numerical values that represent the degree of heat or coldness of an object or environment. It can be measured using various scales, such as Celsius, Fahrenheit, or Kelvin, providing precise numerical data. Qualitative descriptions, on the other hand, would involve subjective terms like "hot" or "cold," which do not offer specific measurements.
All flames are hot
Quantitative is basically the numbers and figures of whatever you have done.Qualitative is the verbal use, so words and descriptions for what you've done.E.g.At school, we did an experiment:Purpose: to see if you put one hand in cold water and one hand in hot water for 30 seconds and then put them both in tap water, would one be hotter than the other?So the quantitative results would be what temperature the water was, how much water there was etc.The qualitative results would be whether you felt the water was hotter or not etc.
That flame is the source of heat for the hot air in the hot air balloon.
The top of of the flame has the highest temperature.
70 degrees and the roaring flame is 100 degrees so yeah hot hot dont touch
