What happens during an exothermic reaction
Heat is given off during an exothermic reaction. Heat is
absorbed during an endothermic reaction
How do raidiators in homes transfer heat
Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic waves.
What is the transfer of thermal energy between touching objects
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C
specific heat(;
your welcome!
How does a substance change when its thermal energy changes
For example, when heat energy (thermal energy) is added to a
substance, either its temperature will increase, or it will change
its state (as when ice is melted).
What is the total kinetic energy of the atoms and molecules in an object called
Temperature is the measure of average kinetic energy of all the
atoms and molecules in an object
What is the type of heat transfer through movement of liquids and gases
What describes a radioisotope
An isotope of an element that is radioactive
What variable represents specific heat in the equation Q mcT
What does it mean for an element to undergo transmutation
an element becomes a totally different element..
What is the half life of a radioisotope if a 20 g sample becomes 10 g after 16 hours
The half-life is 16 hours.
What is a decay chain
One element decaying into another, which decays into another
In a nuclear fission reaction a freely moving neutron is introduced to nuclear fuel such as uranium 235 what happens next
A neutron is absorbed by an atoms nucleus
A worker at a nuclear power plant has noticed that his dosimeter alarm has been activated. What might this indicate
Answer this question…
Radiation is being released from the reactor.
What phase has the lowest entropy
What is the half life of a radioistope
The amount of times it takes for a half of the material to
decay.
