Physics

Which of the following normally warms up fastest when heat is applied?

iron

A temperature difference of 10 Celsius degrees is also equal to a temperature difference of 10 on the

kelvin scale

Temperature is most closely related to molecular

kinetic energy

Place a 1-kilogram block of iron at 40°C into 1 kilogram of water at 20°C and the final temperature of the two becomes

less than 30 degrees C

The white-hot sparks from a 4th-of-July-type sparkler that strike your skin transfer

little energy to you in spite of their high temperature.

One of water's interesting thermal properties is that when heated it takes a relatively

long time in changing temperature

The fact that desert sand is very hot in the day and very cold at night is evidence that the specific heat capacity of sand is relatively

low

A substance that cools down faster than others has a

low specific heat capacity

A substance that heats up relatively quickly has a

low specific heat capacity.

If the specific heat of water were lower than it is, ponds in the cold winter would be

more likely to freeze

Pour two liters of water at 40°C into one liter of water at 20°C and the final temperature of the two becomes

more than 30 degrees C

The air in your room is composed of molecules that have

wide variety of speeds

Room temperature on the Kelvin scale is about

300K

The amount of heat needed to raise the temperature of 1 gram of water by 1°C is

4.19 joules

When 10 grams of hot water cool by 1°C, the amount of heat given off is

41.9 joules

The quantity of heat that a substance can transfer relates to its

all of the above

Pour a liter of water at 40°C into a liter of water at 20°C and the final temperature of the two becomes

at or about 30 degreesC

Heat energy is measured in units of

both of these

In which is the temperature greater?

both the same

Which unit represents the most energy?

calorie

Which temperature scales have equal sized degrees?

celcius and kelvin

Aluminum has a specific heat capacity more than twice that of copper. Place equal masses of aluminum and copper wire in a flame and the one to undergo the fastest increase in temperature will be

copper

Which temperature scale has the smallest sized degrees?

fahrenheit

When you touch a hot potato with your finger, energy flows

from the potato to your finger

When you touch a cold piece of ice with your finger, energy flows

from your finger to the ice

A substance that heats up relatively slowly has a

high specific heat capacity

the moderate temperatures of islands throughout the world has much to do with water'

high specific heat capacity

Compared to a giant iceberg, a hot cup of coffee has

higher temp but less internal energy

Aluminum has a higher specific heat capacity than iron. This means that for equal masses of aluminum and iron, the metal that heats more quickly when the same amount of heat is applied is

iron

If the specific heat capacity of water were lower than it is, a nice hot bath would be a

shorter experience

If the specific heat capacity of water were lower than it is, a watermelon in a picnic cooler would cool in a

shorter time

The specific heat capacity is highest for substances that absorb or release large quantities of heat for correspondingly

small temp changes

Heat energy travels from an object with a high

temperature to an object with a lower temperature.

Tomatoes have a higher specific heat capacity than dough. This means that when you bite into a hot pizza

the tomato sauce feels hotter than the dough

The fact that a thermometer "takes its own temperature" illustrates

thermal equilibrium
