Predict whether a greater amount of energy will be trans ferred as heat between 1 kg of water at 10C and a freezer at -15C or between 1kg of water at 60C and an oven at 65C?

The formula for determining the amount of heat energy is q = m x C x ΔT, where
q = amount of heat energy gained or lost by a substance, m = mass of substance in grams, C = heat capacity (J/g •oC), and ΔT is the change in temperature. If all other variables are the same, then the greatest change in temperature will cause the greatest amount of energy gained or lost. The water that went from 10oC to -15oC had the greatest change in temperature and the greatest change in energy.

∙ 11y agoThe 1kg of water at 10c and a freezer at -15c will have a greater ammount of energy being transfered...There is a greater difference in the temps. And with both of them having the same mass, the greater temp diff would win!

Can you use mass alone to predict whether an object will sink or float?
No. An object will sink if its DENSITY is greater than that of the liquid (or gas) in which you place it.
How can one predict whether an object will float or sink in a liquid?
An object will sink if its density is greater than the liquid in which it is placed; it will float if its density is less.
Predict whether a solenoid suspended by a string could be used as a compass?
yes it can
How can you use density of an objectto predict whether it will float or sink?
if the object is more dense the liquid it is in it will sink. if it is less dense than the liquid it is in it will float
Predict whether sound will travel faster in the air in the summer or the winter?
Summer because the air particles are more spread out and can move faster in more heat

How can you use an activity series of elements to predict whether a given reaction will occur and what the products will be?
An activity series is used to predict whether metals will displace hydrogen gas from water and acid solutions. It is also used to predict whether metals will displace other metals.
How can density be used to predict whether on object will float you sink in water?
Because that's how life is. If the density is greater than the density of water it will sink. If less, it will float.
What does Gibbs energy predict?
It predicts whether or not a reaction will be spontaneous.
Can you use volume alone predict whether an object will sink or float?
No, because you can predict if an object will sink or float mostly on density.
What does the gibbs free energy predict?
It predicts whether or not a reaction will be spontaneous.
Is it safe to keep a freezer temp At 37?
The answer is no whether you mean Fahrenheit or Centigrade.
Can meteorologists predict volcanoes?
The fact of whether or not geologists can measure or predict a valcano is silly each valcano is different and it is of nature thus there is not way to predict what it will do and when it will do it.
How can a table listing of metals in an activity series be useful for prending whether a chemical reaction will occur?
An activity series of metals can predict whether a replacement (displacement) reaction will occur. You use the activity series to compare the reactivity of different metals in order to predict whether a replacement reaction will occur. A metal that is above another metal in the series will replace that metal in a compound.
Predict whether a solenoid suspended by a string could be used as a compass?
yes it can
What can be used to predict whether most single replacement reactions will take place?
combustion
