Heat and Thermodynamics II - SS1 Physics Past Questions and Answers - page 1
Thermal equilibrium is a state in which:
Heat is transferred from a colder object to a hotter object
Temperature remains constant over time
The temperature of an object increases indefinitely
Heat is completely absent from a system
Which of the following is a temperature scale based on the properties of gases?
Celsius
Kelvin
Fahrenheit
Rankine
The melting point of ice is _______ on the Celsius scale and _______ on the Kelvin scale.
0°C, 273 K
0 K, 273°C
100°C, 373 K
100 K, 373°C
Which temperature scale is commonly used in scientific and engineering calculations?
Celsius
Kelvin
Fahrenheit
Rankine
Thermal equilibrium between two objects occurs when:
They have the same mass
They have the same volume
They have the same temperature
They have the same density
The absolute zero temperature is:
0°C
-273°C
0 K
-273 K
Which temperature scale uses the freezing and boiling points of water as reference points?
Celsius
Kelvin
Fahrenheit
Rankine
The conversion formula from Celsius to Kelvin is:
K = °C + 273
K = °C - 273
K = °C + 32
K = °C - 32
The relationship between the Celsius and Fahrenheit scales is given by the formula:
°F = (9/5) × °C + 32
°F = (5/9) × °C - 32
°C = (9/5) × (°F - 32)
°C = (5/9) × (°F + 32)
The Kelvin scale is an absolute temperature scale because:
It has a fixed zero point at absolute zero
It uses the properties of water for reference
It is widely used in everyday life
It is based on the properties of gases
