Which measurement temperature or volume limits the precision of your data?
Volume because in experimentation the temperature depends on the volumes of the two substances being used
List two substances that are solids two that are liquid and two that are gases at room temperature?
aluminum and rock juice and milk oxygen and nitrogen
Can two substances have the same specific heat?
It will be having different temperature, but same thermal energy and same temperature, but different thermal energy
When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
a chemical change occurs
Why are two substances more poisonous than just the two substances by themseves?
Two is more stronger themselves
Suppose that 28 g of each of the following substances is initially at 27.0circ C What is the final temperature of each substance upon absorbing 2.45 kJ of heat?
We can answer this one of two ways. The first way we can do the experiment to a 'T' to find out the final temperature, or we can use the formula provided with our lab.
Why is it important to observe temperature change when two chemical are mixed?
The temperature change is needed to calculate the enthalpy change.
How do you calculate the concentration of two mixed solutions?
calculate final molarity of the solution if 11ml of 5m solution is made up to 20ml
Which measurement temperature or volume limits the precision of your data?
Volume because in experimentation the temperature depends on the volumes of the two substances being used
List two substances that are solids two that are liquid and two that are gases at room temperature?
aluminum and rock juice and milk oxygen and nitrogen
Temperature glide in an zeotropic refrigerant menas the refrigerant is a?
a mixture of two or more substances of different properties.
What are two of the four factors that can influence the rate of a reaction?
The concentration of the substances that react is one. The temperature is another.
What are two substances that are solids and that are at room temperature?
Plastic, most metals (aluminum, tin, copper, etc.)
How long does heat flow to one substance into another?
Until the two substances reach the same temperature.
Can heat transfer occur when two substances are the same temperature?
yes your mum had heat transfer with your dad
When two or more substances are combined the temperature of the reaction will?
Combination of two or more compounds is generally an exothermic process but endothermic processes exist.
When two or more substances are combined will the temperature rise or fall?
Combination of two or more compounds is generally an exothermic process but endothermic processes exist.
