Term1/13

Thermal conductors are substances that do what

Definition1/13

They are good and conducting and transferring heat.

Term1/13

Which is the temperature that Fahrenheit and Celsius thermometers would read as the same number

Definition1/13

-40o C

Term1/13

Pouring water on yourself and drying naturally vs toweling off cools you because

Definition1/13

the water's latent heat of vaporization is being pulled from your body, the water is using heat to undergo a phase change.

Term1/13

A horizontal line on a phase change graph indicates

Definition1/13

A horizontal line on a phase change graph means there has been no change. Often longer periods of research are needed to see significant change.

Term1/13

What would happen to the pressure inside any enclosures on the moon as the sun hits the exterior and the temperature begins to rise

Definition1/13

The gasses inside the enclosure would expand as their molecules were excited creating a greater pressure inside the enclosures.

Term1/13

Metal ice-cube tray and a plastic tub of ice cream are sitting in the freezer Why does the ice-cube tray feel colder to touch than the tub of ice cream

Definition1/13

The metal ice-cube tray has a higher conductivity

Term1/13

What does temperature decrease on

Definition1/13

it depends on the temperature because if it is a cold temperature the temperature will decrease.

Term1/13

On a cold winter day the cold from the outside moves into the house primarily through the windows

Definition1/13

It’s definitely false ‼️(Apex)

Term1/13

What is the balanced equation of HC2H3O2 and NaHCO3

Definition1/13

NaHCO3 + HC2H3O2 = NaC2H3O2 +H2O+CO2

Term1/13

Why do railroad tracks buckle on very hot days

Definition1/13

Most materials, steel included, expand on heating. The expansion causes the buckling.

Term1/13

What word mean neither good or bad

Definition1/13

neutral

benign

neutral

benign

Term1/13

What type of base will clean a rusty iron

Definition1/13

slake lime [NaOH]

Term1/13

On a very hot summer day railroad tracks can buckle causing train delay and derailments select the what the best reason below for the buckling
