Some examples of things that do not change when they are warmed include abstract concepts like emotions or thoughts, as well as certain physical properties of pure substances such as density or mass.
The process is a physical process and the actual change is a physical change.
When liquid oxygen is warmed, it evaporates and turns back into gaseous oxygen. This is because the boiling point of oxygen is -183 degrees Celsius, so any increase in temperature above this point will cause it to change state.
Air gets warmed and cleaned as it passes through the nasal cavity, where it is humidified, filtered, and warmed by the mucus and tiny hairs called cilia. Additionally, the air is further warmed and cleaned in the trachea and bronchi by the same mechanisms of mucus and cilia before reaching the lungs.
When the atmosphere is warmed by the sun, the air expands and becomes less dense, leading to a decrease in air pressure. This change in air pressure can cause air to rise, creating areas of low pressure. As a result, cooler, denser air moves in to replace the rising warm air, which can lead to wind and various weather patterns, including the development of clouds and precipitation.
When ice is warmed, it undergoes a phase change from solid to liquid, a process known as melting. The method involved in this transition is called thermal conduction, where heat is transferred to the ice, increasing the kinetic energy of its molecules. As the temperature rises to 0°C (32°F), the ice absorbs heat and eventually transforms into water.
If water is warmed up, then that means that its temperature does change.

The state of matter that shows the largest change in volume when warmed or cooled is gas. Liquids and solids increase and decrease in volume in response to temperature change as well, but not to the same magnitude as gases.
This is a physical process.

The sidewalk being warmed by the heat of the sun is a physical process. The sun's rays transfer heat energy to the sidewalk through radiation, causing the molecules in the sidewalk to vibrate more rapidly and increase in temperature. This is a physical change as no new substances are being formed in this process.
