Which material would require the least amount of energy to change 1kg from a solid to a liquid ethanol aluminum propane or water?
Water would require the least amount of energy to change 1kg from a solid to a liquid because it has a lower melting point compared to the other materials listed (ethanol, aluminum, propane).
The energy produced when 1kg of a substance is fully converted into enetgy is?
The energy produced when 1kg of a substance is fully converted into energy is given by Einstein's famous equation E=mc^2, where E is the energy produced, m is the mass of the substance (1kg in this case), and c is the speed of light. This equation shows that a large amount of energy can be generated from a small amount of mass.
Which fluid will float 5 kg of ethanol or 1kg of water?
1 kg of water will float in ethanol because ethanol is less dense than water.
Will glucose or sucrose under go more fermentation?
Sucrose is a double sugar and one molecule of sucrose is broken into one molecule of glucose and one molecule of fructose by the yeast (with and enzyme called invertase) prior to fermentation. From a pure chemical reaction perspective 1kg of can produce slightly more alcohol than 1kg of glucose, but given the right environment yeast can fully ferment both. Most brewers yeast prefers glucose to fructose so the glucose will be tend to be consumed first. Glucose is more expensive than sucrose so sucrose is a more cost effective choice.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.
Which is lighter 1kg of gold or 1kg of iron?
1kg of gold and 1kg of iron weigh the same amount because they both weigh 1 kilogram. The difference between the two lies in their density and value, not in their weight.
Which is heavier 1kg or 700g?
1kg = 1000g
If you consume 1kg of any food it is possible to gain more than 1kg in weight?
The amount of weight gained is dependent on the amount of calories in a food, not the weight of the food itself. 3500 calories equals 1 lb, or .45 kg.
What does 1M glucose solution mean?
1M glucose means that 1 mole of glucose is dissolved in 1kg of water. Since 1M means 1 molal. And molality is equla to no.of moles of solute per kg of water.
What is the amount of energy needed to raise the temperature of 1kg of water by 1 degree Celsius?
phase change
What is specific latent heat.?
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
