Explanation

To arrange the given statements in sequence of increasing order of heat content, we need to understand the heat content of different states of water (ice, water, and steam) at various temperatures. The heat content is influenced by both the state of the substance and its temperature.

### Step-by-Step Solution:

1. **Identify the States and Temperatures**:
- (a) Ice at `10°C`
- (b) Water at `10°C`
- (c) Ice at `40°C`
- (d) Water at `40°C`
- (e) Steam at `10°C`

2. **Understand Heat Content**:
- Ice has lower heat content compared to water at the same temperature because ice is a solid and has less kinetic energy.
- Water has higher heat content than ice because it is in a liquid state and has more kinetic energy.
- Steam has the highest heat content because it is in a gaseous state and has the highest kinetic energy among the three states.

3. **Compare the Heat Contents**:
- **Ice at `10°C` (a)**: This has the lowest heat content as it is solid and at a low temperature.
- **Water at `10°C` (b)**: This has more heat content than ice at the same temperature.
- **Ice at `40°C` (c)**: This has more heat content than ice at `10°C` because it is at a higher temperature, but still less than liquid water.
- **Water at `40°C` (d)**: This has even more heat content than ice at `40°C` because it is in a liquid state and at a higher temperature.
- **Steam at `10°C` (e)**: This has the highest heat content as it is in a gaseous state, despite being at a lower temperature than the water at `40°C`.

4. **Arrange in Increasing Order**:
- (a) Ice of 10 g mass at `10°C`
- (b) Water of 10 g mass at `10°C`
- (c) Ice of 10 g mass at `40°C`
- (d) Water of 10 g mass at `40°C`
- (e) Steam of 10 g mass at `10°C`

### Final Order:
1. (a) Ice at `10°C`
2. (b) Water at `10°C`
3. (c) Ice at `40°C`
4. (d) Water at `40°C`
5. (e) Steam at `10°C`
