*C= K-273 (the same as) K-273 = *C

What is the freezing point of water in Celsius

0 degrees

On the Celsius scale the freezing point of water is ______________ and the boiling point is _____________

0*C and 100*C

1 joule = ___ calories

0.2390 calories

10^6

1,000,000 (one million)

What is the boiling point of water in Celsius

100 degrees Celsius

10^3

1000, kilo

10^9

1000000000

What is the freezing point of water in Kelvin

273.15 K

On the Kelvin scale the freezing point for water is———————- and the boiling point is _________________

273K and 373.15K

a temperature of 30c is equivalent to______K

303K

If the Normal body temperature is 37* C ? Calculate the temperature in Kelvins.

310K (Use formula K=*C+273) 37*+273 =310K

If normal body temperature is 310K in Kelvins, What is body temperature in Celsius?

37*C (Use formula C=K-273); 310-273 = 37*C

What is the boiling point of water in Kelvin

373.15 K

1 calorie = ____ joules

4.184 joules

Using the Fahrenheit scale what is the normal body temperature?

98.6*F

Gram

A non - SI base unit

Define calorie

The AMOUNT of HEAT that raises the TEMPERATURE or Joules

If you measured both the mass and weight of an object on Earth and on the moon, you would find that....

The mass remains the same, but the weight changes.

What is energy?

the capacity to do work or produce heat

Why is the number 273 used in the formula to convert Celsius to Kelvin or Kelvin to Celsius?

Because 273 is the freezing point of water in Kelvin and 0 is the freezing point in Celsius, the difference between Kelvin and Celsius is always 273 points.

What are the two units scientists use to measure temperature

Celsius (C) and Kelvin (K)

What is another scale we use to measure temperature, but not often used by scientists?

Fahrenheit

Temperature

Is a measure of how hot or cold an object is

What are the 2 units of energy used in chemistry?

Joules and calories

Write the formula and convert 2212*C to Kelvins

K =*C+273 ; 2212+273 = 2485K

Write the formula and convert 960.8*C to Kelvins

K =*C+273 ; 960.8+273 = 1233.8K

What is the formula to convert from Celsius to Kelvin?

K=*C+273 (the same as) *C+273= K
